sim-se: add a release parameter to Process.py
Set the default release to that single value for all ISAs.
glibc has checks for the kernel version based on uname, and refuses
to start any syscall emulation programs if those checks don't pass with
error:
FATAL: kernel too old
The ideal solution to this problem is to actually implement all missing
system calls for the required kernel version and bumping the release
accordingly.
However, it is very hard to implement all missing syscalls and verify
compliance.
Previously, we have simply bumped the version manually from time to
time when major glibc versions started breaking.
This commit alleviates the problem in two ways.
Firstly, having a single kernel version for all versions means that it is
easier to bump all versions at once.
Secondly, it makes it is possible to set the release with a parameter,
which in turn can be set from the command line with:
se.py --param 'system.cpu[:].workload[:].release = "4.18.0"'
