Subject: [PATCH] Fix debug mode build with uClibc
When --enable-debug is passed, liblog4c-localtime wants to use
<mcheck.h>. It takes the precaution of testing if __GLIBC__ is
defined. But unfortunately, the uClibc C library pretends to be
compatible with glibc by defining __GLIBC__, but it doesn't provide
mcheck.h.
To better support this situation, we add an AC_CHECK_HEADERS() check
on mcheck.h, and then use HAVE_MCHECK_H were appropriate.
Submitted upstream: https://github.com/rcmadruga/log4c-localtime/pull/1
