4Subject: [PATCH 45/46] libgcc: Add knob to use ldbl-128 on ppc
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
