Well, I don't like those macros too, but they *are* useful for
cross-OS/distro portability and I understand what someone means when
saying this:

(a)  Having to set PATH etc. for an RPM build is not done, IMHO,
     and you can simply give examples where the PATH order gives
     for different tools results you might not want (e.g. you
     want make from /usr/local/bin and perl from /usr/bin, while
     there is a perl in /usr/local/bin that you do not want to use).

(b)  If you want to use, say, a local "make" (e.g. GNU make on a
     UNIX system has no GNU tools) and you have that installed in,
     say, /opt/gnu/make/bin/make (just a weird example, fill in
     yourself), then you are able to use a RPM build environment
     with %__make defines as /opt/gnu/make/bin/make.
