Install GHC from source with profiling build of base

When I build GHC from source, I can see a bunch of .p_hi files under libraries/base. This makes sense given that the default for GhcLibWays is "v p". But when I run "make install" all the profiling stuff gets stripped out: amartin@thadtop:~/.local/lib/ghc-8.9.0.20190628$ find . | grep -o '\.[^./0-9]*$' | sort -u . .a .cache .conf .d .dyn_hi .h .hi .lock .o .so .txt Not a profiling-related artifact in sight. And this local build rightfully fails to build anything with profiling turned on. So, how do I actually install the profiling builds of the wired in libraries? -- -Andrew Thaddeus Martin
