Richard Biener 0bb163df97 bootstrap/119680 - fix cross-compiler build with --enable-host-shared 
It seems that at least when cross-compiling at least collect2 pulls
in objects from libbacktrace.a which is linked via LIBDEPS.  But
libbacktrace for the host is only built -fPIC with --enable-host-shared
but not -fPIE with --enable-host-pie so this fails.  The following
teaches libbacktrace about --enable-host-pie and handles it similar
to libcpp.

	PR bootstrap/119680
libbacktrace/
	* configure.ac (--enable-host-pie): Handle by setting PIC_FLAG
	to -fPIE.
	* configure: Regenerate.

Richard Biener 9ae4f4ae44 [libbacktrace] fix up broken test 
zstdtest has some inline data where some testcases lack the
uncompressed length field.  Thus it computes that but still
ends up allocating memory for the uncompressed buffer based on
that (zero) length.  Oops.  Causes memory corruption if the
allocator returns non-NULL.

libbacktrace/
	* zstdtest.c (test_samples): Properly compute the allocation
	size for the uncompressed data.
