New Revision: 229532
URL: http://svn.freebsd.org/changeset/base/229532
Log:
now picobsd cross builds work (tried with host amd64, target i386 ).
The fix involved adding a proper build of ld-elf.so.1 ,
and also replacing ldd with objdump (suggested by Garrett Cooper)
to build the list of shared libraries needed by the binaries
and libraries on the target.
