I think we should just remove the checks.  They are run on all platforms
even though only relevant to one, and they can in any case be specified
via -with-blas=foo for some `foo' (cxml or dxml, I think).

> case a specific platform (or even in combo with a specific compiler).

Even though we are in feature free, zapping the following lines in
m4/R.m4 seems innocent enough:

if test "x$BLAS_LIBS" = x; then
  # BLAS in Alpha CXML library?
  AC_CHECK_LIB(cxml, $dgemm_func, BLAS_LIBS="-lcxml", , $FLIBS)
fi

if test "x$BLAS_LIBS" = x; then
  # BLAS in Alpha DXML library? (now called CXML, see above)
  AC_CHECK_LIB(dxml, $dgemm_func, BLAS_LIBS="-ldxml", , $FLIBS)
fi

If we do this, we need to add the info to R-admin.texi.
