bug#28827: 26.0.60; compilation mode -vs- messages from make

[Tom Tromey]

I'm using an Emacs built from the emacs 26 branch.
I have GNU make 4.2.1.

When I compile, if I get an error, make also prints this, e.g.:

make: *** [Makefile:1928: breakpoint.o] Error 1


In the *compilation* buffer, the "*** [Makefile:" text is highlighted
red.

When I next-error, Emacs will ask me:

Find this error in (default *** [Makefile): ~/gdb/build/gdb

However, this sort of error is basically never interesting, as it's not
a bug in the Makefile; it is just make reporting which rule
failed... but I already know which rule failed from the earlier
messages.

I think it would be an improvement if compilation mode ignored these
messages.

Tom
