[U-Boot] Build failure with u-boot master branch

[maitysanchayan at gmail.com]

Hello,

I have been working on adding DCU support for Vybrid and during the process
of rebasing to latest master for sending out patches, the build for u-boot 
master branch fails with the following error

  HOSTCC  tools/gpimage-common.o

config file is colibri_vf_defconfig.

The earlier commit which worked for me was

    Merge branch 'master' of git://git.denx.de/u-boot-spi

Is this is a known issue with a fix?

Thanks & Regards,
Sanchayan.
