The rationale why people are doing so has always escaped me. Would you
mind to explain why you are doing this?

Correct. However, the error above indicates you likely are using
outdated sources/patches and outdated rpm.specs.

The breakdown above is caused by an incompatiblity between gdb-6.8 and
CentOS 6's readline (CentOS 6 ships readline 6, while gdb-6.8 expects
readline 5 and can't cope with readline 6).
[Or differently: Vanilla gdb-4.8 is too outdated to be compilable on
"not-so-outdated" OSes such as CentOS 6]
Patches addressing this issue should be part of the rtems-4.9-gdb's
patches and later versions of gdb.
