Subject: rtems/bsps: Fix building 3rd party packages with various options

- Fix locating valid tools and BSP. If either is found in the
  staging area use that else use the specific --with-* option
  and if not present use the --prefix.

- Locate the tools by checking if the arch's C compiler is a valid
  file. No other checks are made on the tools.

- Locate a BSB by checking for a valid pkgconfig file for the
  BSP.

- Only filter flags if the BSP is in the staging area

Closes #3893
