Hi Piyush.

This patch adds new DejaGnu target board for BPF for runtime testing of
BPF programs using the `bpf-vmtest-tool` script in the contrib directory.
The kernel version used for the tests can be specified via KERNEL_VERSION,
for example:
make check-gcc RUNTESTFLAGS="--target_board=bpf bpf-torture.exp 
KERNEL_VERSION=6.14"

If not specified, the default kernel version used is 6.15.

It also adds a new torture subdirectory for running torture tests on BPF 
programs.
Passed tests covered in bpf.exp and bpf-torture.exp

gcc/ChangeLog:

        * Makefile.in: Append boards directory to target boards search path.

gcc/testsuite/ChangeLog:

        * boards/bpf.exp: New board for bpf-unknown-none target
        * gcc.target/bpf/torture/bpf-testool-demo.c: New test.
        * gcc.target/bpf/torture/bpf-torture.exp: New test.


The board should be contributed to dejagnu rather than GCC.
We already have a bpf-sim.exp board there.

I was not able to find bpf-sim.exp in the master branch of dejagnu, but 
I found an existing patch for it: 
https://lists.gnu.org/archive/html/dejagnu/2020-09/msg00001.html


I will update this commit based on the bpf-sim.exp patch and submit a 
patch to dejagnu.

Thanks
