[OpenBIOS] [PATCH 1/1] [FCODE-utils] Allow overriding more Makefile vars

[Peter Lemenkov]

As a package maintainer I'd like to override some more Makefile
variables. Namely:

* DESTDIR
* strip command invokation (ability to suppress it by passing /bin/true
  instead of /bin/strip)
* pass custom gcc flags

This patch allows this. It does not break any existing workflows where
it's not required to change these variables.
