2017-06-28Use autoconf header detection correctly for libmissingDavid Oberhollenzer
AC_CHECK_HEADERS already makes sure our config header contains a HAVE_$FOO_H macro if a header was found. There is no need to awkwardly set our own Automake conditionals and check for it all over the place in the Automake files. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2016-11-17Add libmissingDavid Oberhollenzer
This patch adds a libmissing library to mtd-utils, containing implementations of functionality found in glibc but typically missing from embedded C libraries such as uclibc ot musl. For now, the library only contains stub implementations of the backtrace*() family of functions.
