Subject: [PATCH] add Wl,-z,noseparate-code for so
binutils 2.31 add a separate-code(default)/noseparate-code link option to separate
.rodata from .text segment. Cause this is a dubious feature that intends to
reduce the number of ROP gadgets, and this will reduce batch program's
performance, like unixbench shell program, it will reduce 8%~10%. So
add 'Wl,-z,noseparate-code' to disable this feature.
