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