this is bloating the configure script + configure help.  Just use:
	LDFLAGS=-lmcheck ./configure ...

Yes:

But I do not find it so important to make a configure option to it.

Given that --disable-libmcheck for snapshot may make some sense I do not
oppose it but I do not think it is worth it, it is a corner case where one can
edit configure or Makefile IMO.

I understand the reason is to workaround current GDB bugs exposed by -lmcheck.
This is sure not the right solution.
