Details:
upgrading from make-3.81 to make-3.82 seems to break the origin marking of
variables and thus command line variable overriding. using glibc here as my
example.
to reproduce (warning: do not run as root):
tar xf glibc-2.11.2.tar.bz2
cd glibc-2.11.2
mkdir build
cd build
../configure --prefix=/usr -q
sed -i '/^install_root/{h;s:.*:$(warning install_root=$(install_root)
origin=$(origin install_root)):;H;x;H;x}' config.make
make install-headers install_root=$PWD/foo
the local config.make file has a default:
install_root =
but we're overriding it on the command line, so that should always be
ignored
glibc will basically do a `make -C ..`, and here you'll see the correct
behavior:
.../config.make:8: install_root=$PWD/foo origin=command line
.../config.make:10: install_root=$PWD/foo origin=command line
but the makefile logic in there depends on generated files. so make will
generate those files, leave the subdir, and then re-enter it. upon re-entry
though, we now see:
.../config.make:8: install_root=$PWD/foo origin=environment
.../config.make:10: install_root= origin=file
obviously that is incorrect ;)
