strongswan: add a PACKAGECONFIG for libbfd stack traces

Browse Source 
Strongswan installs a signal handler for SIGSEGV, SIGILL, and SIGBUS
which attempts to print a stack trace of the crash. For producing line
numbers in the stack trace, it can use libbfd from binutils, or
libunwind, or else it falls back to a slower method using
/usr/bin/addr2line.

Currently the addr2line method is unlikely to actually work, since there
is no RDEPENDS to pull that command into the image.

This patch adds a PACKAGECONFIG to enable the libbfd-based stack traces,
which is likely the best alternative since binutils is already required
for building everything, and it will be faster than the addr2line method
(which requires addr2line and libbfd anyway).
