Performance optimization for applications with lot of shared library
dependencies. See http://www.akkadia.org/drepper/dsohowto.pdf
config ADK_DEBUG
bool "Compile applications with debug support and do not strip"
help
All software for the target will be compiled with:
-fno-omit-frame-pointer
-funwind-tables
-fasynchronous-unwind-tables
Software will not be stripped.
Mostly useful for NFS root or big USB/CF or hard disk setups.

help
All packages and C library will be compiled with debug information,
but stripped for the target.

bool "Link applications statically by default"
select BUSYBOX_STATIC
help
Useful for debugging of dynamic linker problems. Be aware of the fact, that uClibc and glibc
still requires libgcc_so.so.1 for pthread_cancel. Glibc also requires libnss_*.so libraries
at runtime. Full static builds are only supported for musl libc.

If you want to create more portable toolchains, build them static.
