RFR: 8006808 mapfile use check in jdk/make/common/shared/Defs-solaris.gmk is throwing 'egrep: syntax error'

[Tim Bell]

Hello

http://bugs.sun.com/view_bug.do?bug_id=8006808

This check only worked as intended on Solaris/SPARC.  For non-SPARC 
architecture, egrep throws "egrep: syntax error" and the mapfile check 
is skipped.

The solution is to provide a search pattern in the else that is 
acceptable to egrep:

Thanks in advance for any feedback.
