When compiling natively (target=#f in Guix parlance), this is perfectly fine. However, when cross-compiling, there is a problem. "which" looks in $PATH for binaries. That's good for purpose (1), but incorrect for (2), as the $PATH contains binaries from native-inputs instead of inputs. This commit defines a ‘search-input-file’ procedure. It functions like 'which', but instead of searching in $PATH, it searches in the 'inputs' of the build phase, which must be passed to ‘search-input-file’ as an argument. Also, the file name must include "bin/" or "sbin/" as appropriate. * guix/build/utils.scm (search-input-f
