It has been added by
http://git.buildroot.net/buildroot/commit/target/linux/Makefile.in?id=ea8b1fa6a60705eedc5bd4f405f45c8f531c2126,
which is a bit limited in details on why it was needed. I guess the
goal was to tell the Linux build process to use the lzma utility built
for the host by Buildroot, in case the Linux kernel is built (or the
initramfs) with LZMA compression. But that remains to be verified.
