Subject: powerpc:GCC(<10) doesn't allow -mlong-double-64 after -mabi=ieeelongdouble
X-Git-Tag: glibc-2.38~222
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=36cc908ed549389713955093bbfeaa35fdaf3e2e;p=thirdparty%2Fglibc.git

powerpc:GCC(<10) doesn't allow -mlong-double-64 after -mabi=ieeelongdouble

Removed -mabi=ieeelongdouble on failing tests. It resolves the error.
error: ‘-mabi=ieeelongdouble’ requires ‘-mlong-double-128’
