Details

Description:

As it is now, R is compiled without memory profiling capabilities. Trying to use the `profmem` package to profile different expressions returns the following:

```
"Error in profmem_begin(threshold = threshold) :
Profiling of memory allocations is not supported on this R system (capabilities('profmem') reports FALSE). See help('tracemem'). To enable memory profiling for R on Linux, R needs to be configured and built using './configure --enable-memory-profiling'."
```

This capability would be nice to have when developing R packages from archlinux, as right now we can only profile time, not memory, and sometimes memory usage in R is more important than time.

Additional info:
* package version(s)
community/r 4.2.1-1
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:
* Install `profmem` package
* Execute `profmem::profmem({rnorm(10)})`
* Error message as above is shown
This task depends upon
