Subject: [PATCH 0/3] bugs exposed by higher levels of compiler optimization

When switching optimization to higher levels (-O3) and enable link
time optimization (-flto) gcc found some things to complain, but which
are easily repaired with the following three patches.

The first two, concern minor bugs in musl that are exposed by
optimization; potentially optimized variables across longjmp or

The third, concerns a bug in ld, but which is easily circumvented.

Jens Gustedt (3):
  protect some clobbered variables with volatile
  Have different definitions of __pthread_tsd_main agree in size
  use the real symbol name for environ in execvp
