Some compilers will allow the -o flag with the -c flag. It allows more
control over where the output goes.

However, if you look in the Makefile for GNU Make 3.27 you will find a
comment that says to add "-DNO_MINUS_C_MINUS_O" to the CFLAGS when
building GNU Make if your compiler does not support -c and -o
together.
