Grip doesn't cross-build or recompile anything so there are no
optimisations available that would require changing any of the binary
files within Grip.

Only Crush provides any opportunity to recompile any source code.

Any options related to variants of the existing architectures need to
be made such that normal Debian tools will accept the new architecture.
I'm not entirely sure what you are requesting but it would appear that
you need dpkg-architecture to be able to support the modified values.
That can be done via dpkg-cross support but you haven't provided enough
information to work out what you require or how to begin that process.

? -march ? What options to glibc?

emchain relies on the architecture support of dpkg-architecture and
dpkg-cross.
