WiP: Transcient build test of flashrom against Dasharo/flashrom@5111246…

… to test https://github.com/Dasharo/flashrom/tree/kgpe-patch-rebase

Pointing to Dasharo/flashrom#11 so that CircleCI shows success where work is happening

Changes:
- "WARNERROR=no" is a env variable interpreted at compilation now, not a configuration option anymore
- To work around heads pkg-config, newer flashrom needs to have LIBS_BASE overriden to detect proper libusb and libpci as installed under heads/install
- INSTALL="$(INSTALL)" DESTDIR="$(INSTALL)" CFLAGS="-I$(INSTALL)/include/libusb-1.0 -I$(INSTALL)/include/pci" and LDFLAGS="-L$(INSTALL)/lib" needs to be passed as env variable  to build properly
- flashrom module now depends on libusb, since flashrom looks for pkg-config of installed libusb as prereq
