+Subject: [PATCH] libgcc: do not build 128-bit long double runtime support for
+ musl
+
+Another patch was already disabling 128-bit long doubles for the
+compiler itself, this one additionally avoids building the runtime
+support for that.
+
+Musl does not support 128-bit long doubles, and building libgcc
+with 128-bit long double ABI was breaking things like ld.gold
+which refuses to link two objects with different FP ABI tags.
