Alan Modra c20a064233 Configury changes for obstack optimization
Provides defines used to determine whether glibc obstacks are
compatible.  Generally speaking, 32-bit targets won't need to use
obstack.o from libiberty if glibc is used, while 64-bit targets will,
until glibc gets the new obstack code.

	* configure: Regenerate.

Joel Brobecker 82ef0f7074 Do not use libiberty's getpagesize on Android
Building libiberty on Android currently fails with the error message
shown below.  This was discovered by trying to build GDBserver
for Android, which stopped building after libiberty became
a GDBserver dependency.

Here is the error message:

[...]/getpagesize.c:64:1: error: redefinition of 'getpagesize'
In file included from /[...]/getpagesize.c:34:0:
/[...]/usr/include/unistd.h:171:23: note: previous definition of 'getpagesize' was here

And looking at the definition, one can see that it defined as
a static inline function...

   static __inline__ int getpagesize(void) {
     extern unsigned int __page_size;
     return __page_size;
   }

... which explains why the AC_CHECK_FUNCS test failed to detect
the function, since there is no associated symbol to be linked in.

This patch prevents getpagesize.c to be compiled in by hard-coding
the fact that getpagesize is available on android hosts.

libiberty/ChangeLog:

        * configure.ac: Set AC_CV_FUNC_GETPAGESIZE to "yes" on
        Android hosts.
        * configure: Regenerate.

Mike Frysinger 369be6981b libiberty: fix --enable-install-libiberty flag [PR 56780]
Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted.  So we end up initializing properly
at the top only to reset it at the end all the time.
