It all kinds of boils down to this bug with the configuration of our base system copy of gcc: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192394 .

The prefixing/sysroot isn’t being setup properly, which means that you have to use $PATH to tell gcc and friends which tool you want to use (which make buildworld, etc does). One way to fix this (if we used autoconf in the base system build) would be to reconfigure it with a particular sysroot:

$ ./configure --help | grep -A 3 sysroot
  --with-build-sysroot=sysroot
                          use sysroot as the system root during the build
  --with-sysroot=DIR Search for usr/lib, usr/include, et al, within DIR.
  --with-gnu-ld           assume the C compiler uses GNU ld default=no
  --with-libiconv-prefix[=DIR]  search for libiconv in DIR/include and DIR/lib
  --without-libiconv-prefix     don't search for libiconv in includedir and libdir
$ svn info configure | grep ^URL:
URL: svn+ssh://ngie@svn.freebsd.org/base/head/contrib/gcc/configure

I believe clang is smart enough to compile/link because it is setup to grok multiple formats, but I’ll defer to the clang team to definitively state whether or not that’s the case.

Thanks!
