[RFR]: 8187004: No valid toolchains defined for BSD

[John Paul Adrian Glaubitz]

Hello!

I started working on fixing OpenJDK on BSD today and already ran into
the first issue which is the configure script being unable to find a
usable toolchain.

This happens because there are no valid toolchains defined for BSD in
common/autoconf/toolchain.m4. Since both clang and gcc are supported
on most BSD systems, this can be trivially resolved with:

diff -r 1147dee33745 common/autoconf/toolchain.m4
