package/gcc: fix gcc 8.4, 9.3 and 10.2 for sparcv8 (ss10)
As reported on IRC by sephthir, the qemu_sparc_ss10_defconfig doesn't
work as expected: the system generated when booted under Qemu produces
illegal instruction messages.
gcc 8.3, 9.2 are the latest working gcc version. git bisect between
gcc 8.3 and 8.4 allowed to identify the commit that introcuced the
regression.
Reverting this patch allowed to produce a working rootfs.
