adjust mips crt_arch entry point asm to avoid assembler bugs
apparently the .gpword directive does not work reliably with local text labels; values produced were offset by 64k from the correct value, resulting in incorrect computation of the got pointer at runtime. instead, use an external label so that the assembler does not munge the relocation; the linker will then get it right. commit 6fef8cafbd0f6f185897bc87feb1ff66e2e204e1 exposed this issue by removing the old, non-PIE-compatible handwritten crt1.s, which was not affected. presumably mips PIE executables (using Scrt1.o produced from crt_arch.h) were already affected at the time.
