mpdecimal: fix build on pure static library configurations

This commit adds a patch to mpdecimal that makes it understand --enable-shared/--disable-shared and --enable-static/--disable-static, even if mpdecimal isn't using automake/libtool. It allows to build only the static variant of the mpdecimal library when needed.

+Subject: [PATCH] Add minimal support for --{enable,disable}-{shared,static}
+
+mpdecimal uses autoconf, but not automake or libtool, so this commit
+adds some basic handling of --{enable,disable}-{shared,static}, so
+that building the shared library can be disabled in pure static
+library contexts.
