Seconded. I do exactly that in another recent package where I needed another
"verboten" idiom available only in the widespread and feature-rich GNU make
but not the so-much-more constrained basic make: if statements.
See https://github.com/eddelbuettel/Rblpapi/blob/master/configure where I
need to encode 32 or 64 in the name of shared library. By relying on Rscript
I code around the constraint of not having GNU make. [ That is still a
non-CRAN package but for an unrelated, different reason. ]
