# since it might end up loading libraries from a different Glibc. So

# put *only* libpthread in LD_LIBRARY_PATH (via $out/lib2). !!! This

|
# is a temporary fix (since /bin/sh could have a dependency on
|
|
# libpthread as well). A better fix would be to make patchelf work on
|
|
# libraries, or to set the RPATH rather than the RUNPATH in the
|
|
# binaries in $out/bin (patchelf --force-rpath doesn't quite work,
|

# since it doesn't discard the existing RUNPATH).
