Subject: [PATCH 2/3] modpost: remove self-definitions of R_ARM_* macros

Commit f5983dab0ead ("modpost: define more R_ARM_* for old
distributions") added self-definitions for the R_ARM_* macros to fix
build errors on CentOS 7.

RHEL/CentOS 7 were retired at the end of June.

Remove all the R_ARM_* definitions (except for R_ARM_THM_CALL), which
should be available in recent distributions.

Glibc added most of R_ARM_* macros in 2013. [1]
