x86/vdso/kbuild: Group non-standard build attributes and primary object file rules together
The fresh changes to the vDSO Makefile in:
289d0a475c3e ("x86/vdso: Use CONFIG_COMPAT_32 to specify vdso32")
329b77b59f83 ("x86/vdso: Simplify obj-y addition")
Conflicted with a pending change in:
b388e57d4628e ("x86/vdso: Fix rethunk patching for vdso-image-{32,64}.o")
Which was resolved in a simple fasion in this merge commit:
f14df823a61e ("Merge branch 'x86/vdso' into x86/core, to resolve conflict and to prepare for dependent changes")
.. but all these changes make me look and notice a bit of historic baggage
left in the Makefile:
- Disordered build rules where non-standard build attributes relating to
were placed sometimes several lines after - and sometimes *before*
the .o build rules of the object files... Functional but inconsistent.
- Inconsistent vertical spacing, stray whitespaces, inconsistent spelling
of 'vDSO' over the years, a few spelling mistakes and inconsistent
capitalization of comment blocks.
Tidy it all up. No functional changes intended.
