That is rather unlikely as I explained here 


when rejecting that PR. Which came unannounced and undiscussed, which is
generally a bad idea; always preferable to file an issue ticket fist, or
discuss here as you did.

Changing this creates extra work for me as I need to clean the shell script
of things bash has for free.  I happen to like bash as a basic shell.

If your system is large enough to have room for R and extra packages, I'd
argue that it should have room for bash too: per the respective Debian/Ubuntu
packages size, bash is actually smaller than RcppArmadillo.  And if you
really can't then you can always locally patch the tarball.

At some point this test will go away and we'll just assume a good enough LAPACK.
