[Bug libc/1139] New: libc uses calloc upon initialization in _dl_tls_setup


First i hope i'm correct here with this bug report. The problem is libc uses
calloc upon initialization, to be exact in the function _dl_tls_setup in
dl-tls.c. This can cause problems with code that tries to find memory leaks and
so provides it's own malloc/calloc/etc. functions since those functions might
not be working yet on init of libc. A example is the trace-malloc code from
Mozilla, glibc calls calloc upon init while NSPR (that's the very core of
Mozilla) is not initialized yet which crashes it, see
https://bugzilla.mozilla.org/show_bug.cgi?id=295159 for the bug report on this.
Maybe this calloc call on init could be avoided?
