Bugzilla Bug 134063

sci-libs/gsl fail to build with --as-needed ld flag, the attached patches have
been extracted from a suse src rpm and works for me.
The patch should work also with previous versions of the library w/o changes.

One side note, the rpm specs contain:
------------------------
%ifarch i386 x86_64
# We could add -msse2 -mpfmath=sse here ...
CFLAGS="$RPM_OPT_FLAGS -O3 -finline-limit=720 --param max-inline-insns-auto=160
-ffast-math -funroll-loops -fno-strict-aliasing -momit-leaf-frame-pointer
-funit-at-a-time -ftree-vectorize" ./configure  --enable-shared --with-gnu-ld \
        --prefix=/usr --mandir=%{_mandir} --infodir=%{_infodir} 
--libdir=%{_libdir}
%else
CFLAGS="$RPM_OPT_FLAGS -O3 -finline-limit=720 --param max-inline-insns-auto=160
-funroll-loops -fno-strict-aliasing -funit-at-a-time -ftree-vectorize"
./configure  --enable-shared --with-gnu-ld \
        --prefix=/usr --mandir=%{_mandir} --infodir=%{_infodir}
--libdir=%{_libdir}
%endif
------------------------

so maybe it's now possible to remove the filtering of richer CFLAGS (untested
here).
