[companion-integrate] RTI - Minor fix to pkgdefs/Makefile

[Steven M. Christensen]

This is a RTI for a fix to the pkgdefs/Makefile.  An extra \ somehow 
found its way into the pkgdefs/Makefile file.  This has been removed.

This change and been reviewed and approved by Paul Cunningham.

This makes no difference to nightly builds.
