Cool.

Maybe add "check-unit" to the echo string, so that "make check" output is more
understandable?

Done.

I have something similar in a patch -- which I reproduce here:
UNITTEST_SRCS = \
        BitcodeMunge.cpp \
        IceELFSectionTest.cpp \
        IceParseInstsTest.cpp

# PATCH-BEGIN
# The X86 assembler tests take too long to compile. Given how infrequently the
# assembler will change, we disable them. Furthermore, they are completely
# disabled in non-DEBUG builds. The compiler goes bananas with so many
# optimization oportunities, and eventually freezes the entire machine.
ifdef CHECK_X86_ASM
ifndef DEBUG
$(info X86 Assembler tests not available in non-debug build.)
else
UNITTEST_SRCS += AssemblerX8632/LowLevel.cpp \
        AssemblerX8632/DataMov.cpp \
        AssemblerX8632/Locked.cpp \
        AssemblerX8632/GPRArith.cpp \
        AssemblerX8632/XmmArith.cpp \

We can merge to yours when the time comes. Mine is a bit more aggressive.
