Submitted by: Ryan Oliver <ryan.oliver@pha.com.au>
Date: 2007-02-14
Initial Package Version: 4.2.0
Origin: Ryan Oliver (issue reported by Erik-Jan Post)
        Rediffed against 4.1.0 by Chris Staub
        Rediffed against 4.1.2 by Jim Gifford
        Rediffed against 4.2.0 by Joe Ciccone
Upstream Status: N/A
Description:
  Removes standard_exec_prefix_2 from library search path when cross-compiling.
  Removes both standard_exec_prefix_1 and standard_exec_prefix_2 from the gcc
  executable search path when cross-compiling.

  ie: if cross_compile = 1 in the specs file, do not
      - do not add /usr/lib/gcc/${TARGET}/${GCC_VER} to the library search path
      - do not add /usr/lib/gcc/${TARGET}/${GCC_VER} or
                   /usr/libexec/gcc/${TARGET}/${GCC_VER}
        to the executable search path

  This avoids the possibility of linking in libraries from the host if they
  exist under those directories.
