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 Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>
