Testsuite failure in gdb.mi/mi-var-child.exp

Testsuite failure in gdb.mi/mi-var-child.exp

[Andreas Schwab]

On systems with function descriptors a function value is printed like
"@0x40000000000014a0: 0x4000000000000a90 <nothing>".  This isn't matched
by "$hex <nothing>".

And that appears to be a feature, since it's handled specially in
c-valprint.c.

Whoops, the missing ", Inc." means that the copyright update script
missed it.
