Some software, like libmicrohttpd, check in there configure script if
_REENTRANT is correctly defined. This might be wrong, but I guess riscv-linux
should just behave like other platforms.

Could someone with commit rights please backport this to the gcc 7 branch?

Note that _REENTRANT is a no-op with glibc 2.25 or later unless you 
specifically select an old standard version (in which case it's an alias 
for _POSIX_C_SOURCE=199506L).

Does it need to define it?
