Allow files to be compiled in parallel

[schloerke]

I ran across an error while checking reverse dependencies for shiny.

If I have MAKE=make -j10 set (allow 10 items to compile at once), I run into an error:

ERROR: compilation failed for package ‘frailtypack’
* removing ‘/shiny/revdep/checks.noindex.nosync/frailtypack/new/frailtypack.Rcheck/frailtypack’

If I unset the MAKE value in ~/.Renviron, the package compiles as expected.

It would be great if failtypack would also work with a larger j make value.

Thank you!
