fix: failure of make engine test when a make engine alias contains a modifier. There can be more than one variant per alias via "." e.g. make.extrastuff where make and extrastuff are variants.

# This BSF file is to support building for ARMV6 architecture. The options specified here are same as for ARMV5 except
# the --cpu 6 option in INVARIANT_OPTIONS. This specifies to compiler to compile for generic ARMV6. If any other
# specific options are required such as --cpu ARM1136J-S, --memaccess -UL41, etc, then it can be done via a different
# BSF file
