Subject: [Buildroot] [PATCH 6/8] arch/mips: some variants need different gcc versions
Date: Sun,  3 Sep 2017 11:44:32 +0200	[thread overview]
Message-ID: <e8749f1349de2add1313bf1632dd1a4a1249da2d.1504431850.git.yann.morin.1998@free.fr> (raw)
In-Reply-To: <cover.1504431850.git.yann.morin.1998@free.fr>

We use the conditions currently expressed in the gcc version choice.

We leave the msul vs mips64 conditions in gcc, because the "fault"
really is on gcc, which does not recognise the mips64+musl tuples,
so the fix lie with gcc, and the current conditions are fitting.
