The complete patch is below my signature. I also noticed that on
Linux systems "-Wl,-rpath,..." sets the RPATH property in the ELF
object, which cannot be preempted via LD_LIBRARY_PATH. This is
deprecated, and one is encourated to use the new RUNPATH property
instead which has lower precedence than LD_LIBRARY_PATH. Since
Postfix uses the build-tree libraries during the build, we need
LD_LIBRARY_PATH to work. Therefore, for Linux 3 systems (likely
more similar systems also need this) I added -Wl,--enable-new-dtags
to SHLIB_LD.
Anyone know which version of the toolchain introduces --enable-new-dtags?
