Summary: app cpufrequtils in Blackfin app programs fails to build in FDPIC
Details:
using default config and enable USER_CPUFREQUTILS in Blackfin app programs, it
fails to build for fdpic formats. Flat format is OK. It is not a regression result.
Bellow is the log:

The same problem for lib bitvector with flat format. FDPIC is ok.

it really isnt the same problem at all. please file a different bug for
libldap.
these packages are building shared libs all the time regardless of FDPIC vs
FLAT, but how the package controls that setting may differ greatly.
--- Vivi Li 2009-06-02 02:09:28
Hi, Mike
I can see such problems in the following libs: bitvector, ldap, nl, pcre. Do I
need to file different bugs for each of them?

--- Sonic Zhang 2009-06-02 02:14:43
You may file a new bug and list all these libraries together.
--- Vivi Li 2009-06-02 07:10:58
OK. Pleas refer to bug 5194.
