[yocto] [meta-freescale] Including Static Libraries from sysroot in an autotools based package

[Priya Agarwal]

I have edited the Makefile.am as well in this way:

squid_LDADD += -lusdpaa_of

Then I just retarred squid code and build it again.

And The libraries are shown in the compile command as well, when I see the
log.do_compile generated during the build.
Check Line number 403 in this pastebin link. (ctrl+F 'usdpaa_of' could show
where all it occurs). http://pastebin.com/LpaymTQa
So how is it possible they are not actually linked.
I even checked the OVERRIDE variable in bitbake.conf which is set
correctly.
I really need to link this library. :/
