The GCC package has a default conf option of disabling libquadmath and the toolchain dependencies selectively enabled it if i386 / x64. Fixes: https://gitlab.com/bootlin/toolchains-builder/-/jobs/729359622 This patch fixes a build failure when (GCC + glibc) is being built for the IBM Power8 arch and has libgfortran enabled + libquadmath disabled. The libgfortran has a code condition for __float128 and includes the quadmath headers. The bug occurs because Power8 has emulated float128 support. The fix per GCC options is to also set --disable-libquadmath-support which disables the __float128/libquadmath support in gcc/fortran and in libgfortran [1]. Another option to fix the build failure was to enable libquadmath for IBM Power8 (ISA 2.07), however this would be soft float based as the ISA 3.0+ (Power9) first supports native float128 [2][3].
