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].
