Alexey Neyman 99283866cc Add patches to Linaro GCC
Same as the base release as long as they applied.
MUSL patches didn't, removed.

Also, unobsolete Linaro GCC5 now that they rolled out a new release.

Subject: [PATCH] libgcc: fix DWARF compilation with FDPIC targets
The build of unwind-dw2-fde-dip.c currently fails for FDPIC targets with
the following error:
libgcc/unwind-dw2-fde-dip.c:167:31: error: storage size of 'load_base' isn't known
struct elf32_fdpic_loadaddr load_base;
This patch addresses that by defining load_base with the appropriate
type on FDPIC targets. It has been tested on FRV and Blackfin.
Fixes PR gcc/68468.
