Excuse me, I want to consult one thing: I installed raw microblaze cross
compiler, binutils and glibc into one directory (/upstream/release), and
try to build a "Hello world" C program for microblaze under x86_64 host.
I guess it is OK, but I am not quite sure about it (I use raw compiler,
and have to point out "/upstream/release/lib/ld.so.1" explicitly, and
receive a warning related with 'ld').
Is it really OK? can I still use raw compiler for our testsuite? Is
'LinkScr.ld' for ldscript related with current case?

Generally, you should use "gcc" to link programs, not "ld". gcc is
a driver which will select the appropriate libraries and support routines
(such as crt0.o, which contains _start) and pass them to the linker.
