XIP code may execute with the MMU off, in which case all memory accesses should be strictly aligned to their size. Some versions of GCC violate this restriction even when -mstrict-align is passed, when performing loads and stores that involve SIMD registers. This is clearly a bug in the compiler, but we can easily work around it by avoiding SIMD registers altogether when building code that may execute in such a context. So add -mgeneral-regs-only to the AARCH64 XIP CC flags.
