Thomas Petazzoni 4f7249b281 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.

Fixes:

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.
