The GNU glibc qsort function will call malloc in some cases. That makes

I'm posting this for comments in case anybody sees anything wrong with
the implementation. I'll commit it in a day or two if I don't hear
anything.
Bootstrapped and ran libbacktrace and Go tests on
x86_64-unknown-linux-gnu.
Sorry if I missed some messages or I'm just confused, but today I'm
seeing a lot of regressions all of the same form:
libsanitizer/asan/.libs/libasan.so: undefined reference to `backtrace_qsort'
Confirmed in eg:
http://gcc.gnu.org/ml/gcc-testresults/2014-03/msg00399.html
Any idea what's up?
Thanks,
Paolo.
