Subject: [PATCH] configure.ac: try execinfo in libc before searching
 libexecinfo

execinfo is provided by glibc, so the usual case is that it is part of
libc. Do this before starting a redundant search for libexecinfo.

This is especially relevant for cross-compilation, where
FR_SMART_CHECK_LIB can find an incompatible library.
