Hi, This patch adds runtime support for BPF target tests. Changes in contrib/bpf-vmtest-tool since the previous patch : https://gcc.gnu.org/pipermail/gcc-patches/2025-July/688467.html
- Added a VMTEST_ prefix to environment variables used to customize the host compiler. This avoids conflicts with Makefile, which sets LDFLAGS to an empty string when invoking targets, interfering with the bpf-vmtest-tool LDFLAGS and affecting the host compiler used for loader compilation. - Unset GCC_EXEC_PREFIX when calling the host compiler, as DejaGnu sets it via site.exp and it breaks loader compilation.
