Description Ke Yu 2011-08-10 23:32:35 UTC 
In the qemux86-64 lib64 multilib case, gcc-cross-intermediate has build failure: 

| mv: cannot stat `/home/kyu3/sdb/multilib2/tmp/work/x86_64-pokymllib64-linux/lib64-gcc-cross-intermediate-4.6.1+svnr175454-r4/image/home/kyu3/sdb/     multilib2/tmp/sysroots/x86_64-linux/usr/x86_64-pokymllib64-linux/lib64/*': No such file or directory                                                    NOTE: package lib64-gcc-cross-intermediate-4.6.1+svnr175454-r4: task do_install: Failed

Reproduce step:
commit: 786033f53cad2a196ae6f3a05574148578ea3894 
enable multilib in local.conf:

MACHINE = "qemux86-64"
require conf/multilib.conf
MULTILIBS = "multilib:lib64"
DEFAULTTUNE_virtclass-multilib-lib64 = "x86-64"

# bitbake lib64-core-image-sato

    gcc: use ${base_lib} to match gcc default configuration

    Rather than tweaking MULTILIB_DIRNAMES & MULTILIB_OSDIRNAMES like is
    done for x86-64 via 64bithack.patch.  We can just go with gcc defaults
    and utilize ${base_lib} for where to find gcc libs.

the reason is that: ${baselib} is lib64 in multilib case, while the files to be moved is still in ${D}${exec_prefix}/${TARGET_SYS}/lib/*,  so mv will fail.
