Summary: Makefile: remove -Werror, change to -O2, make clean
Original Submission: For gcc, -O3 or higher means "inline everything", which
for code such as compilers/assemblers which contain lots of function calls
often cause worse performance due to cache effects, and more importantly, adds
a lot to the code size (35% on Linux/x86-64, 47% on Linux/i386) for no
measurable gain -- especially given that it might cause code to be evicted from
the L1 I$.
-Werror breaks compiling on some broken platforms, e.g. Cygwin, which otherwise
would compile correctly but with warnings.
Finally, fix "make clean".
