[cfe-dev] scan-build checking for make

Hi all,

scan-build looks at the name of the build command to decide whether to add 
CC=... and CXX=... commandline options for make-like build commands, in order to 
override these values if they are set in the makefile (which wins over 
environment variables).

https://github.com/llvm/llvm-project/blob/master/clang/tools/scan-build/bin/scan-build#L1118

Unfortunately, this means that

scan-build /usr/local/bin/make or scan-build $HOME/bin/gmake

are not recognized as "make-like" and CC=... and CXX=... options are not added.

This check should be made with a regex, just like the checks before.

Is this Perl script still used? Should I make a patch?
