package/brotli: workaround m68k build issues

Browse Source 
On m68k building with optimizations  results in failures such as:

/tmp/cckiMnG5.s: Assembler messages:
/tmp/cckiMnG5.s:142572: Error: value -39206 out of range
/tmp/cckiMnG5.s:142629: Error: value -40282 out of range

/tmp/cckiMnG5.s:191955: Error: value -40282 out of range
/tmp/cckiMnG5.s:195734: Error: value -53294 out of range

These only appear when building with -O2, the smaller code generated
with -Os does not cause trouble, so workaround by using that.
