[MIPS] Remove TARGET_ASM_FUNCTION_RODATA_SECTION
Since 'Remove obsolete IRIX 6.5 support' [1] we only use gp-relative jump-tables for PIC code. We can fall back to default behaviour for asm_function_rodata_section. [1] https://gcc.gnu.org/ml/libstdc++/2012-03/msg00067.html 2018-06-04 Dragan Mladjenovic <dragan.mladjenovic@rt-rk.com> gcc/ * config/mips/mips.c (mips_function_rodata_section, TARGET_ASM_FUNCTION_RODATA_SECTION): Removed.

The complication here is that, with the combination TARGET_ABICALLS
