I was unaware that oe-core's libgcrypt recipe provides a modified
libgcrypt.m4 in share/aclocal/ that uses pkg-config.

Inspired by the oe-core gnupg recipe, I deleted m4/libgcrypt.m4 from the
libmicrohttpd source directory in a do_configure_prepend and everything now
seems happy.

Thanks, and sorry for the unnecessary diversion.

Mike.
