[PATCH] D42029: [Solaris] Make RHEL devtoolsets handling Linux-specific

[Rainer Orth via Phabricator via cfe-commits]

ro created this revision.
ro added reviewers: fedor.sergeev, tstellar, jyknight.

This patch is meant to address the last outstanding review comment on the already approved
(but not yet commited) https://reviews.llvm.org/D35755, namely making the handling of the RHEL
devtoolsets Linux-specific.

Don't know if it's best integrated into the former or applied subsequently.

Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.
