net/megatools: unbreak on gcc archs

Hi,

there have been attempts to unbreak megatools on gcc archs by forcing
C99 mode but this is not enough. -std=c99 disables some extensions used
by this port, namely anonymous unions. -std=gnu99 helps getting past
that, but linking then fails because the code uses _Static_assert from
C11.

So here's a diff to force the use of base-clang or ports-gcc; both
default to -std=gnu11. Drop our only patch while here.

ok?
