Aurelien Jarno 24d8773d06 MIPS: Fix RLIM64_INFINITY constant for O32 and N32 ABIs
Fix the RLIM64_INFINITY constant for O32 and N32 ABIs to match the
kernel one. Change the getrlimit64/setrlimit64 into old compat symbols,
and provide the Linux generic getrlimit64/setrlimit64 functions as
GLIBC_2_19 version.
