[LLVMdev] llvm-ld support of native libraries

What is the current status of llvm-ld's support of native libraries?  I 
have a bytecode file that needs to link against librt.so.  So, I ran:

llvm-ld -native -o x.exe x.bc -L/usr/lib64 -lrt

and I get the following error:

/tmp/ccB7DGu1.o(.text+0x1a3): In function `main':
: undefined reference to `clock_gettime'
/tmp/ccB7DGu1.o(.text+0x6d8): In function `main':
: undefined reference to `clock_gettime'
collect2: ld returned 1 exit status

Is that error occurring because llvm-ld does not support native 
libraries.  I am able to use llc to turn x.bc into native assembly and 
gcc to link the natively assembly against librt.so to get an executable, 
but I was going to use the llvm native backend if possible.
