# The illumos and the Solaris build both use the same GCC-level host triple,
# though different versions of GCC are used and with different configure
# options. To ensure as little accidental cross-pollination as possible, we
# build the illumos toolchain in a specific directory tree and just symlink the
# expected tools into /usr/local/bin at the end. We omit /usr/local/bin from
# PATH here for similar reasons.

#
# NOTE: The compiler version selected here is more specific than might appear.
# GCC 7.X releases do not appear to cross-compile correctly for Solaris
# targets, at least insofar as they refuse to enable TLS in libstdc++. When
# changing the GCC version in future, one must carefully verify that TLS is
# enabled in all of the static libraries we intend to include in output
# binaries.
