I noticed that in the config.h generated for libiberty has HAVE_DECL_ASPRINTF
defined as 0. This hapens because _GNU_SOURCE is not used when running the
test programs.
Another long-staying bug in the libiberty configure system is that it
claims newlib missing 'asprintf()', 'strdup()' and 'vasprintf()' and
therefore tries to produce these although one has used the
'--with-newlib' in the GCC configure ! AFAIK, only those functions
which are missing from the C library, should be built into libiberty.
The result from this has been the GCC build crashing with the clashing
newlib headers prototypes and the function reimplementations in
libiberty. Sometimes I even made diffs for the fixes in 'configure.ac':
