Bugzilla Bug 176811

When compiling asterisk with h323 use flag turned on linking fails when
compiling chan_h323.

Reproducible: Always

Steps to Reproduce:
1. emerge asterisk
2.
3.

Actual Results:  
Compile fails.

Expected Results:  
Successful install.

When "H.323 wrapper lib" is compiled it says:
 * Building H.323 wrapper lib...
make: Entering directory
`/var/tmp/portage/net-misc/asterisk-1.2.17/work/asterisk-1.2.17/channels/h323'

make: Leaving directory
`/var/tmp/portage/net-misc/asterisk-1.2.17/work/asterisk-1.2.17/channels/h323'

Note missing -fPIC

It later fails when compiling chan_h323:

I'm not sure if the problem is with the ebuild or it is with the makefile(s) in
channels/h323.

I have tried to manually compile the libchanh323.a file with -fPIC which fixes
the problem.

Should be fixed in 1.2.21.1 in a few minutes when the updated patch hits the
tree, thanks to stkn!
