Subject: [PATCH] Makefile: Fix broken build
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

make -C mybuilddir no longer works (regression caused by commit)
388d475815c23901010a25c845eb078d47ee0740.

PWD is the directory of the caller (not mybuilddir),
so BUILD_DIR is set to the wrong value.

GNU make sets CURDIR to the correct value.
Use this macro instead of PWD.
