Subject: [PATCH] Fix use of compact eh frames on MIPS

Newer MIPS toolchains use a different (compact) eh_frame format.
|
||
|
|
libffi don't like them, so we have to switch to the older format.
|
||
|
|
|
||
|
|
This patch add -mno-compact-eh to CFLAGS when compiling for
|
||
|
|
Mips and compiler support it.
