That is because of this automake-generated rule:

The trouble is that "undefine" is an operator in GNU make.
The most pragmatic work-around is to rename the "undefine" test script.
However, Stephano, as automake maintainer, I think you will want to
fix automake not to prohibit the use of such test names.
This could be a legitimate bug in GNU make. It's arguable that GNU make
should only consider "undefine" to be an operator in contexts where it
might be an operator. Clearly a prerequisite (or target) named
"undefine" cannot be a make operator.
