OpenWRT or router install

for soft-float i'm getting:

root@OpenWrt:/# ldd /usr/share/java/ejre1.7.0_71/bin/java
ldd: can't open cache '/etc/ld.so.cache'
checking sub-depends for '/lib/libpthread.so.0'
checking sub-depends for 'not found'
checking sub-depends for 'not found'
checking sub-depends for 'not found'
checking sub-depends for '/lib/libgcc_s.so.1'
libpthread.so.0 => /lib/libpthread.so.0 (0x00000000)
libjli.so => not found (0x00000000)
libdl.so.2 => not found (0x00000000)
libc.so.6 => not found (0x00000000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00000000)
not a dynamic executable

hard-float didn't make any difference:
