    Fix ghc-pkg when only prof way is enabled
    
    Summary:
    We saw following errors:
    
    ```
    $ cabal install --disable-library-vanilla --disable-shared --enable-library-profiling
    hashable-1.2.7.0: cannot find any of
    ["libHShashable-1.2.7.0-Q2TKVDwk4GBEHmizb4teZ.a",
     "libHShashable-1.2.7.0-Q2TKVDwk4GBEHmizb4teZ.p_a",
     "libHShashable-1.2.7.0-Q2TKVDwk4GBEHmizb4teZ-ghc8.4.3.so",
     "libHShashable-1.2.7.0-Q2TKVDwk4GBEHmizb4teZ-ghc8.4.3.dylib",
     "HShashable-1.2.7.0-Q2TKVDwk4GBEHmizb4teZ-ghc8.4.3.dll"]
    ```
    
    This is because ghc-pkg is looking for
    `libHShashable-1.2.7.0-Q2TKVDwk4GBEHmizb4teZ.p_a` instead of
    `libHShashable-1.2.7.0-Q2TKVDwk4GBEHmizb4teZ_p.a`.
