Toolchain failed to bootstrap with LP64F and LP64S ABIs.
As reported by Julien in [1]:
Testing the "lp64f" ABI with commands:
cat >.config <<EOF
BR2_loongarch64=y
BR2_LOONGARCH_FPU_32=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y
BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y
BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF=y
BR2_TARGET_ROOTFS_EXT2=y
# BR2_TARGET_ROOTFS_TAR is not set
EOF
make olddefconfig
make
fails in host-gcc-initial with output:
Assembler messages:

/tmp/ccEkwSsD.s:30: Error: register save offset not a multiple of 8

Testing the "lp46s" ABI with commands:
cat >.config <<EOF

See also autobuilder failures with as [3].
This commit marks those ABIs as broken at the moment to allow time
for investigation. Also, since gcc defaults to the "lp64d" ABI which
requires a 64bit FPU is present, the BR2_LOONGARCH_FPU_32 and
BR2_LOONGARCH_FPU_NONE options also needs to be marked as broken
as well. See [4].
