.lib section to work even if the entire section contents are
	written at once.  From Gvran Uddeborg <gvran@uddeborg.pp.se> and

/* The physical address field of a .lib section is used to hold the
number of shared libraries in the section. This code counts the
number of sections being written, and increments the lma field
with the number.
I have found no documentation on the contents of this section.
Experimentation indicates that the section contains zero or more
records, each of which has the following structure:
- a (four byte) word holding the length of this record, in words,
- a word that always seems to be set to "2",
- the path to a shared library, null-terminated and then padded
to a whole word boundary.
bfd_assert calls have been added to alert if an attempt is made
to write a section which doesn't follow these assumptions. The
code has been tested on ISC 4.1 by me, and on SCO by Robert Lipe
<robertl@arnet.com> (Thanks!).
