Subject: [PATCH] configure.ac: restore user CFLAGS before checking functions
AC_CHECK_FUNCS([mmap]) on Fedora fails to find mmap() due to missing -fPIC.
/usr/bin/ld: /tmp/ccvNyAcN.o: relocation R_X86_64_PC32 against undefined symbol `mmap@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
We have -fPIC somewhere in default CFLAGS, so just resotre user CFLAGS
before making checks for functions.
