Subject: [PATCH] kbuild: invoke generate_builtin_ranges.awk using gawk explicitly

The gawk utility might be installed in different locations depending
on the distributions, etc.  That means that the locations in the
shebang at the beginning of the generate_builtin_ranges.awk script
may not be correct, causing an error.

Use "gawk -f <script> <args>" instead from the Makefile.vmlinux, so
the $PATH will be used to locate gawk appropriately.
