make: support: use command -v' instead of which'

Browse Source 
`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.
