[PATCH] gdb: Use UNSUPPORTED not FAIL for unsupported target features

[Andrew Burgess <andrew.burgess@embecosm.com>]

If a target does not support making function calls from GDB then we
abandon the gdb.base/callfuncs.exp test file early.  Currently we report
a single FAIL before leaving the test file, this commit changes this to
a single UNSUPPORTED.

gdb/testsuite/ChangeLog:

	* gdb.base/callfuncs.exp: Report unsupported rather than fail for
	unsupported target features.
