Remove FreeBSD checks when defining USE_WCHAR_T.

Browse Source 
The problems the comments in the build systems refer to seem to have been
fixed for years. [1] says the checks in libstdc++ have been improved, and
all supported FreeBSD versions enable wchar_t support unconditionally in
libstdc++. Additionally, this needlessly impacts FreeBSD when libc++ is used
instead of libstdc++.
