RFC: vdso build-id standard location

Hi all-

I've proposed a patch to the Linux kernel:

http://lkml.kernel.org/g/a424b189ce3ced85fe1e82d032a20e765e0fe0d3.1403291930.git.luto@amacapital.net

This patch will cause 'make vdso_install' to install build-id symlinks
to /lib/modules/KERNEL_VERSION/vdso/.build-id

The idea is that gdb on Linux platforms could change its default
build-id search path to include that directory and therefore find vdso
debug info for home-built kernels instead of just for Fedora-style
kernel RPMs.

Is this reasonable?  Is it something that can/should be easily added to gdb?

Thanks,
Andy
