[Pixman] [PATCH] Use AC_LINK_IFELSE to check if the Loongson MMI code can link

From: Markos Chandras <markos.chandras at imgtec.com>

The Loongson code is compiled with -march=loongson2f to enable the MMI
instructions, but binutils refuses to link object code compiled with
different -march settings, leading to link failures later in the
compile. This avoids that problem by checking if we can link code
compiled for Loongson.
