message: build: Fix boost build on some platforms
  When the libpath doesn't line up with the value from config.sub, we don't find
  the correct path to boost's libs. This adds a hack to try another path before
  giving up.
  Should close

  + dnl some arches may advertise a cpu type that doesn't line up with their
  + dnl prefix's cpu type. For example, uname may report armv7l while libs are
  + dnl installed to /usr/lib/arm-linux-gnueabihf. Try getting the compiler's
  + dnl value for an extra chance of finding the correct path.

  dnl first we check the system location for boost libraries
  dnl this location ist chosen if boost libraries are installed with the --layout=system option
  dnl or if you install boost with RPM
