[PATCH] osmo-trx[master]: buildenv: Turn off native architecture builds

buildenv: Turn off native architecture builds

The compiler option -march=native instructs the compiler to auto-optimize
the code for the current build architecture. This is fine for building
and using locally, but contraproductive when generating binary packages.

This commit introduces more general options and also removes --with-sse
from the default configure options and replaces them with $(SIMD_FLAGS),
which also contains a collection of supported SIMD options, so we won't
loose the SSE support.
