We were explicitly passing CC and TARGET_CC to configure but overwrote that decision later by passing CC (with the value of TARGET_CC) directly to a recursive make call. The latter overwrite was introduced because `unexport` alone doesn't work on variables that were specified on a make command line (they are added to MAKEOVERRIDES and passed to further re- cursive make calls). Instead of unexporting random variables, unexport those that were actu- ally passed from payloads/external/Makefile.inc and clear MAKEOVERRIDES. Do not pass OBJDUMP as that is nowhere to be found in the GRUB sources. And, last but not least, add --disable-werror because building GRUB is very susceptible to changes in the flex version.
