[ptxdist] [PATCH 2/2] kernel: Use host-elf-h-compat

[Bernhard Walle <bernhard@bwalle.de>]

Set the host include flags of the Linux kernel so that it finds elf.h in
sysroot-host/include. It's required to specify HOST_EXTRACFLAGS in the
environment rather than as make argument because otherwise += doesn't
work which ends in other build errors (gettext problems).

See also http://article.gmane.org/gmane.linux.kbuild.devel/5210 for a
discussion about HOST_EXTRACFLAGS.
