Subject: elf, uapi: Add definitions for VER_FLG_BASE and VER_FLG_WEAK
X-Git-Tag: v6.15-rc1~202^2~33

elf, uapi: Add definitions for VER_FLG_BASE and VER_FLG_WEAK

The definitions are used by tools/testing/selftests/vDSO/parse_vdso.c.

To be able to build the vDSO selftests without a libc dependency,
add the definitions to the kernels own UAPI headers.
