Subject: [PATCH] Makefile.system: don't specify optimization level
 [buildroot-specific]

Buildroot will pass an optimization level, but it is ignored because the
openblas makefiles _append_ to the flags passed on the command-line.

The CFLAGS/FFLAGS would e.g. contain '-Os -O2' in which -O2 survives.

Remove the optimization level specified in openblas itself.
