Description
In a few places Makefile macro $< is used for target rules.
This is not portable, as POSIX allow $< only for "inference" rules (like general rules '.c.o:' for building any .o file from the .c file with the same name).
GNU make and a few other make implementations support $< for targets, but this is not portable behaviour.
The fix is very simple and obvious.
POSIX specification for makefile syntax: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/make.html
Look for "$<"
