ghc-prof binary package in Ubuntu Focal riscv64

 The Glorious Glasgow Haskell Compilation system (GHC) is a compiler for
 Haskell.
 .
 Haskell is "the" standard lazy functional programming language. The language
 definition and additional documentation can be found in the `haskell-doc'
 package. Alternatively, there is an online version at
 http://haskell.org/onlinereport/.
 .
 This package contains additional profiling libraries. They are only needed,
 if you want to take a closer look on where exactly your program burns CPU
 cycles.
