[PATCH] ARM: Enable frame pointers for arm64

[Sascha Hauer]

stack unwinding on arm64 depends on framepointers, so enable them.

OSELAS.Toolchain-2022.10.0 now defaults to -fomit-frame-pointer whereas
earlier versions default to -fno-omit-frame-pointer. Fix stack
unwinding for new OSELAS.Toolchain and other toolchains which omit
frame pointers by default.
