[OE-core] SDK relocation issues

[Tasslehoff Kjappfot]

I compiled an SDK and extracted/installed it to my source tree instead 
of /usr/local/. I have made /usr/local/oecore-i686 a symlink to the 
actual location. With the latest Dylan this broke.

Denzil:
❯❯❯ ldd arm-angstrom-linux-gnueabi-gcc
     linux-gate.so.1 =>  (0xf771d000)
     libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf7544000) 
/usr/local/oecore-i686/sysroots/i686-angstromsdk-linux/lib/ld-linux.so.2 
=> /lib/ld-linux.so.2 (0xf771e000)

Dylan:
Original location:
❯❯❯ ldd arm-angstrom-linux-gnueabi-gcc
     linux-gate.so.1 =>  (0xf77c4000)
     libc.so.6 => 
/home/tasslehoff/src/pdrepos01/toolchains/oecore-i686/sysroots/i686-angstromsdk-linux/usr/bin/armv7a-vfp-neon-angstrom-linux-gnueabi/./../../../lib/libc.so.6 
(0xf7610000)
 
/home/tasslehoff/src/oe/toolchains/oecore-i686/sysroots/i686-angstromsdk-linux/lib/ld-linux.so.2 
=> /lib/ld-linux.so.2 (0xf77c5000)

If I try to run the toolchain from Dylan on a system where 
/home/tasslehoff/src/oe/toolchains/oecore-i686/sysroots/i686-angstromsdk-linux/lib/ld-linux.so.2 
does not exist, it fails.
