libmicrohttpd: fix thread detection on ARC and Blackfin
Due to compiler deficiences, gcc on ARC and Blackfin doesn't define
_REENTRANT, which the latest version of the ax_pthread.m4
autoconf-archive macros looks at to determine whether thread support is
available or not.
Fixing the compilers is definitely the right thing to do, but it's not
doable for pre-built external toolchains like the Blackfin one, so for
now, we simply define _REENTRANT manually on ARC and Blackfin. If more
packages are affected by this problem, a more general solution will have
to be found.
