For reproducibility, stop encoding the hostname into the libtool script,
this isn't really adding much to debugging and most distros are carrying
such a patch now as reproducibility is important.
* m4/libtool.m4: Delete call to hostname & uname.

This patch adds support for flang compilers. Some specific flags
are needed so these compilers must be handled in a specific way.
By default, the compiler is called 'flang', but ARM releases their
own flang-based compiler called 'armflang'.
Because of the current lack of flang support in libtool, the
generated 'libtool' must be manually modified after 'configure' is
invoked. Such a process is for example described on ARM web site
(it involves the Open MPI library).
Url: https://savannah.gnu.org/patch/?9442
* m4/libtool.m4: Handle *flang.
* -fdiagnostics-color: who doesn't like color? No reason to strip it. This
makes the link phase stick out like a sore thumb if there's warnings emitted.
* -frecord-gcc-switches: we use it in Gentoo to check if a package respects
*FLAGS. Note that we do not need to include -grecord-gcc-switches explicitly
here as -g* is already whitelisted.
* build-aux/ltmain.in: Handle -fdiagnostics-color* & -frecord-gcc-switches.
When use automake to generate Makefile.in from Makefile.am, there
comes below race:
| configure.ac:45: error: required file 'config-h.in' not found
It is because the file config-h.in in updating process by autoheader,
so make automake run after autoheader to avoid the above race.
* Makefile.am: Have $(lt_Makefile_in) depend on $(lt_config_h_in).

autoheader will update ../libtool-2.4.6/libltdl/config-h.in which
autoconf needs, so there comes a race sometimes as below:
| configure.ac:45: error: required file 'config-h.in' not found
| touch '../libtool-2.4.6/libltdl/config-h.in'
So make sure autoheader run before autoconf to avoid this race.
* Makefile.am: Have $(lt_configure) depend on $(lt_config_h_in).

"-fno-sanitize*" options e.g. -fno-sanitize=alignment
or -fno-sanitize-recover=all are used to tune the behvior of
sanitizers in GCC/clang. Let libtool pass these options
to compiler similar to fsanitize=*.
* build-aux/ltmain.in: Handle -fno-sanitize*.

Re-declaring _putenv() without _CRTIMP in strict ANSI mode when using
MinGW resulted in a warning because of a conflict with the previous
declaration that did use _CRTIMP.
Simply add _CRTIMP to our declaration to avoid it.
* build-aux/ltmain.in (func_emit_cwrapperexe_src): Add _CRTIMP to
_putenv() declaration.

This adds support for passing -m elf32_x86_64 vs -m elf_x86_64 to the
linker on hurd-amd64.

* m4/libtool.m4: dd x86_64-gnu* case to pass -m elf32_x86_64 vs
-m elf_x86_64 to linker.
The gnuconfig project recognizes windows* as a host OS to denote native
Windows environments. The commit message makes it sound like LLVM and
Crablang communities will use the 'windows' value, whereas GNU will
continue to use 'mingw'. But I think it's only a matter of time until
people start to pass the option --host=x86_64-pc-windows to configure
scripts. We should be prepared for that.
Url: https://savannah.gnu.org/patch/?10387

Include <string.h> for the strcmp function. This improves C99
compiler compatibility because it avoids an implicit function
declaration.

This fixes some other regular expressions that GNU grep 3.8 does not
warn about (I found them with an even-pickier 'grep').
I did not look systematically for all portability bugs of this form.
Url: https://savannah.gnu.org/patch/index.php?10282
* tests/cdemo.at (allow_undefined_flag):
Prefer } to \} in EREs, as \} is not portable.
* tests/libtool.at (quote shell meta-characters in filenames):
Prefer ] to \] in BREs, as \] is not portable.
GNU grep 3.8 warns about some regular expressions that POSIX says have
undefined effect, e.g., '\-'. Unfortunately Libtool uses regular
expressions of this form. Some unittests now fail, e.g. link-order.at:

* m4/libtool.m4 (_LT_LANG_CXX_CONFIG): Do not use \- in a BRE or ERE,
as this produces undefined results that GNU grep 3.8 warns about.
Use [-] instead.

configure: WARNING: using cross tools not prefixed with host triplet
file isn't platform specific and not usually installed with a host
