cover the case where a subdirectory is also built that needs to be
removed.
Note that there are other macros that we don't control (AC, AM, and/or
LT) that also exhibit this problem that we cannot fix. :-\
Fixes trac:1180.
This commit was SVN r16669.
The following Trac tickets were found above:
Ticket 1180 --> https://svn.open-mpi.org/trac/ompi/ticket/1180
changes. The two Big Changes are elegance (much more re-use of code
rather than cut-n-pasting the same code over and over and over and...)
and enabling cross-compilation for F77 and F90 (because we actually
have to *run* some compiled F77 and F90 programs for some of the
tests, which obviously won't work in a cross-compilation environment
-- so enable the use of config.cache to load such values in
cross-compiling environments).
This commit was SVN r8991.
