[PATCH] pseudo: Ensure the correct libraries are used at runtime

[PATCH] pseudo: Ensure the correct libraries are used at runtime

[Richard Purdie]

There can be a conflict between the nativesdk libc and the host system's
libc. It is assumed the nativesdk version is of an equal or higher version.
This is a particular issue for pseudo if its loading a system binary
since the system's libc might be used of an older verison which would
then confuse libpseudo.so when loaded as a preload.

To avoid this, set LD_LIBRARY_PATH so the nativesdk libc is always
used.

Since we now use --without-rpath, we can remove the MAKEOPTS RPATH workaround.

[YOCTO #2299]

Tested, all of the following commands worked well:

1) runqemu qemux86 bzImage-qemux86.bin core-image-sato-qemux86.ext3
2) pseduo ls
3) runqemu-extract-sdk core-image-sato-sdk-qemuarm-20120412211904.rootfs.tar.bz2 
rootfs_dir
