[coreboot] Kconfig: My clang -print-file-name doesn't output the full path

[Bao, Zheng]

The output of uname on my MacOS.
# uname -a 
Darwin Baos-Mac-Pro.local 13.0.0 Darwin Kernel Version 13.0.0: суббота,  9 ноября 2013 г. 02:42:04 (MSK); root:xnu-2422.1.72_by_bronya_sinetek_anv_rc7/BUILD/obj/RELEASE_X86_64 x86_64

# gcc -print-file-name=libncurses.dylib 
libncurses.dylib
# ls /usr/lib/libncurses.dylib 
/usr/lib/libncurses.dylib

The ld option -lncurses can link the right library.

Is this a bug on my MacOS. If it is, I will stop trying that?
