# Idea behind fipscanister.o is to "seize" the sequestered code between
# known symbols for fingerprinting purposes, which would be commonly
# done with ld -r start.o ... end.o. The latter however presents a minor
# challenge on multi-ABI platforms. As just implied, we'd rather use ld,
# but the trouble is that we don't generally know how ABI-selection
# compiler flag is translated to corresponding linker flag. All compiler
# drivers seem to recognize -r flag and pass it down to linker, but some
# of them, including gcc, erroneously add -lc, as well as run-time
# components, such as crt1.o and alike. Fortunately among those vendor
# compilers which were observed to misinterpret -r flag multi-ABI ones
# are equipped with smart linkers, which don't require any ABI-selection
# flag and simply assume that all objects are of the same type as first
# one in command line. So the idea is to identify gcc and deficient
# vendor compiler drivers...
