+As all invokes all-recursive which uses sub-makes to invoke all-am, the
+resulting makefile wants to build libusb-1.0.la twice. In non-parallel builds
+the second attempt is skipped as the target already exists, but in highly
+parallel builds it's likely that two makes will be building libusb-1.0.la at the
+same time.
+
+Solve this by removing the explicit all target, which as libusb-1.0.dll isn't
+built under Linux is redundant anyway.
