Commit Message

Alex Bennée April 20, 2022, 6:08 p.m. UTC
From: Paolo Bonzini <pbonzini@redhat.com>

Build the "docker.py cc" invocation directly in tests/tcg/configure.sh, and
remove the Makefile.qemu wrapper around Makefile.target.  The config-*.mak
files now include the actual variables used when building the tests, rather
than the CROSS_* variables that Makefile.qemu used to "translate".

This is a first step towards generalizing the cross-compilation infrastructure
so that it can be used for firmware as well.
