sys_errlist in glibc 2.0 is naked. We gave it a version of GLIBC_2.0
when versioning was implemented and we had to increase the size of
sys_errlist. We gave it a new version, GLIBC_2.1. Now sys_errlist is
changed again for some arches. That is where GLIBC_2.3 came from. For
mips, the first supported glibc version after 2.0 is 2.2. That turns
GLIBC_2.1 into GLIBC_2.2 for mips. Since mips's sys_errlist is huge in 
2.2, there is no need to change it in 2.3.
