On SH, we use sed for processing multilibs configuration in
config.gcc.  PR target/44531 is a 4.5/4.6 regression reported
for darwin hosts which have a non-gnu sed.  The 'i' modifier
of the 's' command of sed looks a gnu extension which darwin's
sed doesn't support.  The attached patch uses explicit regular
expressions instead of the 'i' modifier.  It's tested on native
sh4-unknown-linux-gnu, cross combined tree setting on powerpc-
apple-darwin9.8.0 and i686-pc-linux-gnu.  For native sh-linux,
I'm using an unrevied patch in
to avoid bootstrap issue on that target.
Applied on trunk.  I'll apply it to 4.5-branch latter.
