4d16e6f532 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.

58ecbbc3ef package/gcc/9.3.0: fix host-gcc-final when ccache is used
As reported by several Buildroot users [1][2][3], the gcc build
may fail while running selftests makefile target.

The problem only occurs when ccache is used with gcc 9 and 10,
probably due to a race condition.

While debuging with "make -p" we can notice that s-selftest-c target
contain only "cc1" as dependency instead of cc1 and SELFTEST_DEPS [4].

  s-selftest-c: cc1

While the build is failing, the s-selftest-c dependencies recipe is
still running and reported as a bug by make.

  "Dependencies recipe running (THIS IS A BUG)."

A change [5] in gcc 9 seems to introduce the problem since we can't
reproduce this problem with gcc 8.

As suggested by Yann E. MORIN [6], move SELFTEST_DEPS before
including language makefile fragments.

With the fix applied, the s-seltest-c dependency contains
SELFTEST_DEPS value.

  s-selftest-c: cc1 xgcc specs stmp-int-hdrs ../../gcc/testsuite/selftests
