klibc: Pass Optimization with KLIBCOPTFLAGS
Overriding KLIBCOPTFLAGS also meant that -Ox flags
were taken off. Which results in errors like
| usr/dash/shell.h: In function 'max_int_length':
| usr/dash/shell.h:103:25: error: '-mgeneral-regs-only' is incompatible with floating-point code
| return (bytes * 8 - 1) * 0.30102999566398119521 + 14;
| ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
| usr/dash/shell.h:103:25: error: '-mgeneral-regs-only' is incompatible with floating-point argument
