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".
