[OE-core] Toolchain Issues

[Jack Mitchell]

Morning everyone,

I'm trying to create a custom toolchain and sdk for a development board 
and I'm having some issues.

I create my toolchain with the following method:

bitbake image -c populate_sdk

When I try to compile u-boot with the sdk, I recieve the following error:

     Configuring for socfpga_cyclone5 board...
     make[1]: *** [/mnt/SSD/socfpga/u-boot-socfpga.git/spl/u-boot-spl] 
Error 1
     make: *** [spl/u-boot-spl.bin] Error 2
     make: *** [u-boot] Error 1
     arm-oecore-linux-gnueabi-size: './u-boot': No such file
     arm-oecore-linux-gnueabi-ld.bfd: cannot find -lgcc
     make[1]: *** [/mnt/SSD/socfpga/u-boot-socfpga.git/spl/u-boot-spl] 
Error 1
     make: *** [spl/u-boot-spl.bin] Error 2
     make: *** Waiting for unfinished jobs....
     arm-oecore-linux-gnueabi-ld.bfd: cannot find -lgcc
     make: *** [u-boot] Error 1

So I took a look at the gcc -v and it gives me:

[09:14:40 jack u-boot-socfpga.git]$ arm-oecore-linux-gnueabi-gcc -v | 
grep custom

Thread model: posix
gcc version 4.8.1 (GCC)

Now, my toolchain is located in the directory:

/mnt/SSD/socfpga/custom-sdk/1.0-20130715

So, why does most of the GCC version info mention the default directory of:

/mnt/SSD/r0005sdk/1.0-20130715

Is this a bug, or just a quirk? If it's a quirk then why can't u-boot 
find -lgcc on compile?

Cheers,
