Revert "Replace obsolete AX_C_CHECK_FLAG with AX_CHECK_COMPILE_FLAG"

This reverts commit f2a96c0fd0bab7380da67a9616eb04308488ff8f. It uses a
macro AS_VAR_IF which is not available on some development environments
we still support. (Entertainingly, AX_CHECK_COMPILE_FLAG itself only
claims an AC_PREREQ of 2.59 which is probably a bug.)

Files:

• configure.ac (modified) (2 diffs)
• m4/ax_c_check_flag.m4 (added)
• m4/ax_check_flag.m4 (deleted)
