556a0a1104 Revert "make: support: use command -v' instead of which'"
This reverts commit ca6a2907c2.

Switching to using 'command -v' instead of 'which', opened a can of
worms that is hard to fix in a timely manner:

  - recursive call to 'make' from a post-build, post-iamge script, fails
    because of a redefinition of HOSTCC_NOCCACHE (a bug on its own that
    needs a separate fix anyway) [0];

  - 'make' believeing it can call "simple" commands with execve() et al.
    instead of passing them through a shell via system(), and thus
    failing to find 'command' in the PATH [1].

ca6a2907c2 make: support: use command -v' instead of which'
`which' has been discontinued after 2.21 release in 2015 due this (git
repository is empty [1]) and version shipped in Debian produces warning
[2]:

/usr/bin/which: this version of `which' is deprecated; use `command -v' in scripts instead.

`command is POSIX [3] and supported on all common shells (bash, zsh,
dash, busybox sh, mksh).

Patch tested on dash as the default shell.

2218dc85be support/dependencies: add a check for a suitable gzip
Recently, some hash mismatch have been reported, both by users as well
as autobuilder failures, about tarballs generated from git repositories.

This turned out to be caused by users having the 'gzip' command somehow
aliased to 'pigz' (which stand for: parallel implementation of gzip,
which takes advantage of multi-processor system to parallelise the
compression).

Unfortunately, the output of pigz-compressed archives differ from that
of gzip (even though they *are* valid gzip-compressed streams).

Add a dependency check that ensures that gzip is not pigz. If that is
the case, define a conditional dependency to host-gzip, that is used as
a download dependency for packages that will generate compressed files,
i.e. cvs, git, and svn.

Fixes:
