[Bug other/23656] New: Cross-compilation with newlib fails in libiberty

["bart dot vanassche at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

While attempting to generate a cross-compiler, I got a build error in
libiberty/strsignal.c, because newlib has a strsignal() definition but libiberty
does not test for the strsignal() declaration in the newlib headers.
