Add _LT_DECLs for host_os, build_alias, build and build_os.
host_os and build were used in a few occasions in ltmain.m4sh
and affect above-mentioned systems, the others are added for
symmetry and in order to be able to detect cross-compiling.

ar x libfoo.a foo.o will always extract the first foo.o in the

delete only the first foo.o, then rinse and repeat. Also add markers
for the testuite.
* m4/libtool.m4 (_LT_CONFIG): Add a marker so that we can use a sed

$foo must be identical after the following commands:
func_quote_for_eval "$foo"

(func_quote_for_expand): In a similar vein to to func_quote_for_eval,
except that variable expansions are not protected when quoting the

it has been subsumed into func_quote_for_eval.

Without this change, the distributed libtool tarball has a
dependency on autom4te. There was some inconsistency in the
filenames: now we have foo.m4sh -> m4sh -> foo.in -> configure
-> foo[.sh]. Bootstrap runs the m4sh steps and the resulting .in
files are distributed:

stages.

(_LT_LINKER_SHLIBS): Make s390x-ibm-tpf hosts adopt GNU/Linux OS
attributes.

these values, when there is no C++ compiler for example, so we

operation of libtool (neither would work alone). First, there is
a new feature that allows libraries to preopen modules. This
entails a backwards incompatible change to the libltdl API for
separating out the preloaded symbol lists by owner. Second, in
the tradition of "eating our own dogfood", libltdl now preloads
its own dlloaders. The internal API for dlloaders has also had to
change in a backwards incompatible way in support of the new
library preloading feature. If you don't use preloaded libraries,
you needn't change your project sources, though you will need to
recompile against the new libltdl. The API changes are mostly
confined to dlloaders, so you probably needn't worry about those

to load any other preloaded dlloaders.
(lt_dlloader_add): Simplify parameter list. Populate new
fields. Chain new loaders according to priority field.

is discovered.
