This factors --enable-libmcheck related bits from GDB's configure.ac and makes GDBserver use them too. Specifically, the 'development' global is moved to a separate script to it can be sourced by both GDB and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits proper are moved to a new m4 file. I started out by defining 'development' in the m4 file, but in the end decided against it, as a separate script has the advantage that changing it in release branches does not require regenerating configure, unlike today. I had also started out by making the new GDB_AC_LIBMCHECK itself handle the yes/no default fallback depending on release/developement, but since I had split out 'development' to a separate script, and, GDB needs the python checks anyway (hence we'd need to do the python checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no' parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping GDB_AC_LIBMCHECK isolated from the 'development' global. IOW, it's the caller's business to handle it. Tested on x86_64 Fedora 17. Built GDB and GDBserver with and without --enable-libmcheck, and observed --enable-libmcheck overrides the disablement of -lmcheck caused by python supporting threads, and that GDBserver links with -lmcheck when expected. Also observed that changing the 'development' global, and issuing "make" triggers a relink, and '-lmcheck' is included or not from the link accordingly. gdb/ 2013-07-03 Pedro Alves <palves@redhat.com> * Makefile.in (config.status): Depend on development.sh.
