configure: Fix -D_FORTIFY_SOURCE=2 check when CFLAGS contains -Wno-error
If CFLAGS contains -Wno-error, then the check for -D_FORTIFY_SOURCE=2
won't fail when appropriate. E.g., compiling with:
./configure CFLAGS='-Wno-error -O0' &&
Results in a flood of "_FORTIFY_SOURCE requires compiling with
optimization (-O)" warnings.
Make sure we add -Werror after the user-defined CFLAGS.
