[patches] Install extra files for use of mklibs

["Joseph S. Myers" <joseph@xxxxxxxxxxxxxxxx>]

I have applied this patch to make EGLIBC install extra files needed for 
relinking shared libraries: the _pic.a files, the version maps and some 
other objects.

The files are installed in the locations expected by the Debian mklibs 
utility (see <http://packages.qa.debian.org/mklibs>).  I will be 
submitting a patch to the mklibs maintainers with various enhancements and 
bug-fixes relating to use in a cross environment; if not accepted there, 
we'll probably provide the patch from the EGLIBC website.

2008-02-07  Joseph Myers  <joseph@xxxxxxxxxxxxxxxx>

	* Makerules (install-extras, install-map): New variables.
	(installed-libcs): Add libc_pic.a.
	(install-lib): Include _pic.a files for versioned shared
	libraries.
	(install-map-nosubdir, install-extras-nosubdir): Add rules for
	installing extra files.
	(install-no-libc.a-nosubdir): Depend on install-map-nosubdir and
	install-extras-nosubdir.
