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?
