configure.in: Restore CFLAGS before gcc_AC_INITFINI_ARRAY.
* configure.in: Restore CFLAGS before gcc_AC_INITFINI_ARRAY.
Move --enable-initfini-array check ...
* aclocal.m4 (gcc_AC_INITFINI_ARRAY): ... here. Define
HAVE_INITFINI_ARRAY also when --enable-initfini-array is given.
Don't AC_SUBST gcc_cv_initfinit_array. Use AC_TRY_RUN.
* configure: Rebuild.
