[Buildroot] [PATCH 1/3] Fix kexec 'bin-to-hex' build failure

[Bryan Hundven]

During the kexec build, bin-to-hex is built to run on the host to help
generate purgatory.c.
BUILD_CC is set to the same thing as TARGET_CC, which does not run on my
host.
This change sets BUILD_CC to HOSTCC so that bin-to-hex is runnable on
the host.
