manual: compiler flags -D and -L should not be followed by space

* doc/autoconf.texi (Preset Output Variables): Remove space
between -D and -L flags and their arguments, traditional cpp
implementations like Solaris 10, IRIX 6.5, OSF Tru64 5.1D,
AIX 5.3 do not accept it.

uses this variable when compiling or linking programs to test for C features.
If a compiler option affects only the behavior of the preprocessor
(e.g., @option{-D @var{name}}), it should be put into @code{CPPFLAGS}
instead. If it affects only the linker (e.g., @option{-L
@var{directory}}), it should be put into @code{LDFLAGS} instead. If it

it should be put into @code{LDFLAGS} instead. If it
affects only the compiler proper, @code{CFLAGS} is the natural home for
it. If an option affects multiple phases of the compiler, though,
matters get tricky. One approach to put such options directly into
