I am newbee to buildroot. I can see multiple gccs in buildroot. I assume all are for cross compilation. What are the difference between those ? 

buildroot-2012.05/output/host/usr/bin/arm-unknown-linux-uclibcgnueabi-gcc
buildroot-2012.05/output/host/usr/libexec/gcc
buildroot-2012.05/output/host/usr/arm-linux/bin/gcc
buildroot-2012.05/output/host/usr/arm-unknown-linux-uclibcgnueabi/bin/gcc

The one you should use is buildroot-2012.05/output/host/usr/bin/arm-unknown-linux-uclibcgnueabi-gcc. The other ones are purely internals binaries.

Use arm-linux-gcc or arm-buildroot-linux-uclibcgnueabihf-gcc. In fact arm-linux-gcc is soft linked to arm-buildroot-linux-uclibcgnueabihf-gcc.
