help
All software for the target will be compiled with:
-fno-omit-frame-pointer
-funwind-tables

Software will not be stripped.
Mostly useful for NFS root or big USB/CF or hard disk setups.

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.
