automake should be copying those rules into the resulting makefile
without any change (except a @LIB32_TRUE@ prefix which expands to empty
if the conditional is true).  So, the remaining issue should be purely
between GNU make and the file.  Looking at the file closely shows that
the first rule doesn't start its command with a TAB.
