Add GCC compiler option. (#1056)
* GCC support. * Add note about gcc-mips-linux-gnu requirement to README.md. * changes * changes based on Tharo's suggestion * Cant reproduce file_choose.h error. Removing unnecessary -I * changes * wording based on Fig's suggestion * add AVOID_UB for eyes/mouth reordering issue. * remove unneeded flags and deprecate ZAPDFLAGS. * some changes, waiting on prs for the rest * fixes * discard header sections * change section handling in mkldscript * avoid_ub in DmaMgr_GetFileNameImpl * move asm to inline asm (consolidate gcc functions) * change prefix back * remove space * fix warnings * Revert "remove space" This reverts commit94af6977b3. * Revert "fix warnings" This reverts commitd729ddf457. * finish up missing_gcc_functions * revert unwanted mkldscript change * temporary workaround. TODO: Stop the asm processor from choking * fix ido build * Revert "temporary workaround. TODO: Stop the asm processor from choking" This reverts commit9df892b7ac. * review * remove unused line in mkldscript * remove tabs * clarify zf comment * review2 * review * remove duplicate cc_check * vanilla code always come first * std_dma avoid ub * add compiler_gcc to cflags * only use two blocks when necessary * clarify zf comment Co-authored-by: fig02 <fig02srl@gmail.com>
