libubacktrace.so build issue

[Subash T Comerica]

Hi,
I am facing the dreaded /lib/libubacktrace.so missing when I turn on the
with-pcre option while cross-compiling lighttpd.

I have worked with the lighttpd mailing list and confirmed it is not a
lighttpd or libpcre issue.

My uClibc version is 0.9.33.2
My libpcre version is 8.35
My lighttpd version is 1.4.51

For the with-pcre addition, I just followed:
http://fengh2000.blogspot.com/2009/06/how-to-cross-compile-lighttpd-with-pcre.html
and
http://www.ridgesolutions.ie/index.php/2013/06/05/build-cross-compile-lighttpd-for-arm-linux-with-pcre/

Strangely if I copy the libubacktrace.so to my build machine's /lib (with
root perms) the build goes through fine, which obviously is a no-go!
Is there any Makefile patch to remove this ASNEEDED dependency on
libubacktrace as I dont see any backtrace related symbols either in libpcre
or lighttpd source? Are there newer patches like the one referred here(
http://uclibc.10924.n7.nabble.com/PATCH-buildsys-clean-up-libubacktrace-linker-script-handling-td11535.html)
that I am possibly missing?

Did any of you face this error while cross-compiling lighttpd with-pcre?

Any help/suggestions on this is highly appreciated.

Thanks,
Subash
