Subject: remove redundant code in do_dlsym function
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=97b72d22ad53e8f1306bf8e943571b698058f49d;p=android-x86%2Fexternal-musl-libc.git

remove redundant code in do_dlsym function

commit 637dd2d383cc1f63bf02a732f03786857b22c7bd introduced the checks
for RTLD_DEFAULT and RTLD_NEXT here, claiming they fixed a regression,
but the above conditional block clearly already covered these cases,
and removing the checks produces no difference in the generated code.
