Subject: [PATCH] use xtensa-lx106-elf-size to print section sizes

This prints more sections than the ls was and seems like a more
appropriate way to print them, the grap removes debug sections (they
address of 0) and blank lines.  This also avoids printing **, which is
the characters make uses to indicate an failure.
