system/gcc: bump to 8.3.0

These patches have been forward-ported to 8:
    002_all_default-relro.patch
    005_all_default-as-needed.patch
    011_all_default-warn-format-security.patch
    012_all_default-warn-trampolines.patch

We are no longer using fortify-headers, so these patches are no longer needed:
    003_all_default-fortify-source.patch
    050_all_libiberty-asprintf.patch
    053_all_libitm-no-fortify-source.patch

These patches no longer appear necessary:
    067_all_gcc-poison-system-directories.patch
    090_all_pr55930-dependency-tracking.patch
    201-cilkrts.patch
    203-libgcc_s.patch
    207-static-pie.patch

These patches have already been applied upstream:
    204-linux_libc_has_function.patch
    332-gccgo-remove-ustat.patch
    ada-aarch64-multiarch.patch
    ada-fixes.patch
    boehm-gc-musl.patch
    fix-rs6000-pie.patch
    gcc-4.8-build-args.patch
    lra-pentium.patch

These patches are no longer necessary because GCJ has been removed:
    310-build-gcj-s390x.patch
    fix-gcj-iconv-musl.patch
    fix-gcj-musl.patch
    fix-gcj-stdgnu14-link.patch

The rest of the changes are updates from nsz's patchset.

+Subject: [PATCH 12/12] static-pie
+
+in gcc-8 -static means static non-pie, even if -pie or -static-pie
+are specified, -static-pie can be used to build static pie.
+
+in musl toolchains -static -pie always meant static pie, so this
+patch fixes the link specs accordingly, the new -static-pie is just
+an alias to -static -pie.
