[klibc] Kbuild: Add option to install unstripped binaries
The .deb and RPM packaging tools can automatically split
debugging symbols into a separate package. This requires
that binaries and shared libaries are initially installed
unstripped, and that they are given build IDs.
If CONFIG_DEBUG_INFO is defined:
* Add --build-id=sha1 to the linker options
* Don't strip binaries after linking them
