dnl var  .. shell variable to append found files

dnl RTEMS_CHECK_MAKEFILE(path)
dnl Search for Makefile.in's within the directory starting
dnl at path and append an entry for Makefile to global variable 
dnl "makefiles" (from configure.in) for each Makefile.in found

dnl canonicalize target name
dnl NOTE: Most rtems targets do not fullfil autoconf's
dnl target naming conventions "processor-vendor-os"
dnl Therefore autoconf's AC_CANONICAL_TARGET will fail for them
dnl and we have to fix it for rtems ourselves
