Hi David, the ':' is the field separator. Remove the spaces in your example:
-Wl,-rpath=/data/glibc/build/glibc:/data/glibc/build/glibc/math:/data/glibc/build/glibc/elf:/data/glibc/build/glibc/dlfcn:/data/glibc/build/glibc/nss:/data/glibc/build/glibc/nis:/data/glibc/build/glibc/rt:/data/glibc/build/glibc/resolv:/data/glibc/build/glibc/crypt:/data/glibc/build/glibc/nptl
