[PATCH modular 1/4] build.sh: remove CACHE env variable as it is not implementable

[Gaetan Nadon]

The concept of global cache for multiple modules does not exist.

When using --cache-file with the same path, variables with the same
name have their values overwritten on a "last write wins" principle.

For example, this cached variable from clock:
pkg_cv_XFT_LIBS=${pkg_cv_XFT_LIBS='-L/home/nadon/xorg/src/lib -lXft  '}

is overwritten with the value from xdm:
pkg_cv_XFT_LIBS=${pkg_cv_XFT_LIBS='
-L/home/nadon/xorg/src/lib -lXrender -lX11 -lXft  '}

If there is some limited usefulness in specific scanerios, one
can pass the --cache-file option in CONFFLAGS.

This was introduced in commit e5592f548a03e332f2b52f6bd502c4593f7816b3
to improve performance.
