Subject: No Bzip2 shared libraries on macOS systems

Bzip2 has a special/separate Makefile to build shared libraries which
didn't work on a macOS. So with this commit, we are allowing Bzip2 shared
libraries only on macOS systems.

Also, I noticed that macOS's `sed' doesn't have the `-i' option (to do the
change in place within the same file). So we are using `-e' to write the
changed Makefile in a temporary directory, then rename that.

Subject: Reseting path in script to make symbolic links to system programs

Until recently, there was no problem with the `makelink' script of
`dependencies-basic.mk' because it was called on separate recipe lines (and
thus separate shells). But recently we added a call to it within a single
shell (for GCC on Mac OS systems). So a previous call to it would effect
the next call. To fix this, in this commit, we are re-setting PATH to its
original value after each call finishes.
