H.J. Lu e352e7e792 x86: Add ENDBR at function entries 
Intel Control-flow Enforcement Technology (CET):

https://software.intel.com/en-us/articles/intel-sdm

contains shadow stack (SHSTK) and indirect branch tracking (IBT).
When IBT is enabled, all indirect branch targets must start with
ENDBR instruction which is a NOP on non-CET processors.

Closes: https://gitlab.freedesktop.org/mesa/mesa/issues/2538

Adam Jackson 904b03824b linux: Don't emit a .note.ABI-tag section anymore (#26663) 
We don't support pre-2.6 kernels anyway - the install docs say 2.6.28
for DRI - and apparently this confuses ld.so's sorting when multiple
libGLs are installed.  Just remove it.

Note: this is a candidate for the stable branches.
