Subject: build-sys: use full path to python in scripts
X-Git-Tag: v197~40
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=b86d11da802b8ff70784b611aacdaa2d148271b4;ds=inline

build-sys: use full path to python in scripts

Commit c4eb236a2c didn't take into account the situation when the user
sets e.g. PYTHON=python3 (without the full path).  This value would
then be used verbatim for PYTHON_BINARY and in she-bang lines in
scripts, which is incorrect. To fix this, $PYTHON is passed through
which, which expands the path.  If $PYTHON_BINARY is desired which is
not installed on the build system, then PYTHON_BINARY must be set
separately.
