The way WANTLIB* and LIB_DEPENDS were set up, ${COMPILER_LIBCXX} ended
up in WANTLIB-main without gcc-libs ending up in LIB_DEPENDS-main;
pkg_create then failed because it had no way to reach a package
providing libestdc++. This kind of breakage had been spotted in several
ports after switching the C++ ports to "COMPILER = base-clang
ports-gcc". I'm not sure yet how these problems could be avoided.
Maybe additional checks in portcheck(1)?
Anyway, opensmtpd-extras was mechanically switched to COMPILER because
WANTLIB-mysql contained ${COMPILER_LIBCXX}. This is currently not
needed, and since opensmtpd-extras is a C-only port, let's just drop
COMPILER.
