I tried the patch and it looks good. I tried in our full blown application and it works like magic!

Subject: [PATCH 3/3] ldso: exclude -fasynchronous-unwind-tables from ldso CFLAGS

At least on ARM, building the ld.so with -fasynchronous-unwind-tables
for backtrace is creating a dependencies against libc through libgcc_eh.
So it needs to exclude this from the ldso cflags.
