musl only uses PT_GNU_STACK to set default thread stack size and has no

gcc/ChangeLog:
* configure: Regenerate.
* configure.ac: define TARGET_LIBC_GNUSTACK on musl
If musl has no executable stack support, then wouldn't we want this
change to apply to all musl platforms, not just mips?
The original change was MIPS-specific[0] and TARGET_LIBC_GNUSTACK is
only used by mips code today. We could change both cases to be more
generic or keep it MIPS-specific. Dragan, what do you think?
Oh yea, I forgot about that older change. Let me take another looksie.
