Subject: tools/mm: allow users to provide additional cflags/ldflags
Date: Mon, 16 Jan 2023 19:49:21 -0300
Right now there is no way to provide additional cflags/ldflags when
building tools/vm binaries. And using eg. make CFLAGS=<options> will
override the CFLAGS being set in the Makefile, making the build fail since
it requires the include of the ../lib dir (for libapi).
This change then allows you to specify:
CFLAGS=<options> LDFLAGS=<options> make V=1 -C tools/vm
And the options will be correctly appended as can be seen from the
make output.
