configure: add optional --enable-native option to compilation flags

Browse Source 
This patch adds an option to enable native CPU optimizations
by adding -march=native to the compiler flags, tuning the
generated code for the build machine at the expense of portability.

In some tests, especially on wrlib I saw 8% perf improvement.
Should be used by developers or those who recompile wmaker for their own usage.
