sysstat compresses manual pages using the `ZIP` environment variable
unless `COMPRESS_MANPG` is set.
`ZIP` seems to default to xz(1) and is for more than just compressing
manuals.
At least with `documentation.man.mandoc.enable = true;` this renders
them unreadable:
```
$ man -w mpstat
man: outdated mandoc.db lacks mpstat(1) entry, run makewhatis /nix/store/lk0r6ibvkrvaq96gp8h4rqgrd2q0c8q5-system-path/share/man
/nix/store/lk0r6ibvkrvaq96gp8h4rqgrd2q0c8q5-system-path/share/man/man1/mpstat.1.xz
```
(followed by `PAGER` showing compressed mpstat.1.xz content.)
Disable manual page compression during build and thus defer it to Nix:
```
gzipping man pages under /nix/store/wl2dwl1lhs9g5w2d5dhr0pcskp78nz42-sysstat-12.4.5/share/man/
```
This also avoids potential runtime incompatibilites in sysstat
(I am not a `services.systat` user).

Very confusingly, the `isPowerPC` predicate in
`lib/systems/inspect.nix` does *not* match `powerpc64le`!
This is because `isPowerPC` is defined as
isPowerPC = { cpu = cpuTypes.powerpc; };
Where `cpuTypes.powerpc` is:
{ bits = 32; significantByte = bigEndian; family = "power"; };
This means that the `isPowerPC` predicate actually only matches the
subset of machines marketed under this name which happen to be 32-bit
and running in big-endian mode which is equivalent to:
with stdenv.hostPlatform; isPower && isBigEndian && is32bit
This seems like a sharp edge that people could easily cut themselves
on. In fact, that has already happened: in
`linux/kernel/common-config.nix` there is a test which will always
fail:
(stdenv.hostPlatform.isPowerPC && stdenv.hostPlatform.is64bit)
A more subtle case of the strict isPowerPC being used instead of the
moreg general isPower accidentally are the GHC expressions:
Update pkgs/development/compilers/ghc/8.10.7.nix
Update pkgs/development/compilers/ghc/8.8.4.nix
Update pkgs/development/compilers/ghc/9.2.2.nix
Update pkgs/development/compilers/ghc/9.0.2.nix
Update pkgs/development/compilers/ghc/head.nix
Since the remaining legitimate use sites of isPowerPC are so few, remove
the isPowerPC predicate completely. The alternative expression above is
noted in the release notes as an alternative.
