The commit
a76108d05e ("x86/entry/vdso: Move vdso2c to arch/x86/tools")
moved vdso2c to arch/x86/tools/ and commit
93d73005bf ("x86/entry/vdso: Rename vdso_image_* to vdso*_image")
renamed .so files but also dropped vdso2c from
arch/x86/entry/vdso/.gitignore.
It should've moved it to arch/x86/tools/.gitignore instead.
Do that.

A new option is added to the relocs tool called '--realmode'.
This option causes the generation of 16-bit segment relocations
and 32-bit linear relocations for the real-mode code. When
the real-mode code is moved to the low-memory during kernel
initialization, these relocation entries can be used to
relocate the code properly.
In the assembly code 16-bit segment relocations must be relative
to the 'real_mode_seg' absolute symbol. Linear relocations must be
relative to a symbol prefixed with 'pa_'.
16-bit segment relocation is used to load cs:ip in 16-bit code.
Linear relocations are used in the 32-bit code for relocatable
data references. They are declared in the linker script of the
real-mode code.
The relocs tool is moved to arch/x86/tools/relocs.c, and added new
target archscripts that can be used to build scripts needed building
an architecture. be compiled before building the arch/x86 tree.
[ hpa: accelerating this because it detects invalid absolute
relocations, a serious bug in binutils 2.22.52.0.x which currently
produces bad kernels. ]
