The lto plugin currently requires a bootstrap compiler with visibility support:
/vol/gcc/src/gcc-lto/lto-plugin/../gcc/lto/common.c:25: warning: visibility
attribute not supported in this configuration; ignored
Since it is built with -Werror, this causes a bootstrap failure if that support
is missing. This causes problems for Solaris, since the necessary support only
went in in December last year.
