[Darwin, testsuite] Handle Darwin's size command.


This one has been in my patch stack for a long time…

Darwin's "size" command has a different header line, reflecting the Mach-O
section naming conventions.  This causes tests using the command to fail
because scanasm.exp expects and checks specific layout of the header line.

Tested on i686, x86_64 and powerpc darwin and x86_64,powerpc-linux-gnu

OK for trunk?
