Makefile: have local gawk depend on local make being built if in unex…

…pected version.

Maximized boards: have rom hashes outputted under hashes.txt. Still not clear why the Makefile "all" target is not doing that for each target.

- Fixes a bug where "make BOARD=xyz bootstrap" was needed prior of being able to build anything else otherwise HEADS_GAWK was expecting HEADS_MAKE to be built already, which was not the case.
(fixes linuxboot#1126)

- As of now, I do not see any OS make/gawk being used anymore. All modules except coreboot (which uses coreboot buildstack), including musl-cross-make, are being built with local make and local gawk.
Improves linuxboot#936 (comment) which showed that local make (/usb/bin/make, /usr/local/bin/make, /usr/sbin/make, /usr/local/sbin/make and /usr/bin/gawk were called locally. To redo)
