gcc: Fix ldbl-128 support for musl
Let the patch trigger based on target triplet instead of passing via configure, this lets gcc compile for 64bit otherwise it ends up with libgcc build errors error: unable to emulate 'TF' (From OE-Core rev: 2259bf5366a9ff654dfaf15baa5df2d943383ce6) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

4Subject: [PATCH 30/36] libgcc: Add knob to use ldbl-128 on ppc 4Subject: [PATCH 10/12] ldbl128 config
5
6musl does not support ldbl 128 so we can not assume
7that linux as a whole supports ldbl-128 bits, instead
8act upon configure option passed to gcc and assume no
9on musl and yes otherwise if no option is passed since
10default behaviour is to assume ldbl128 it does not
11change the defaults
