Added a new config variable CHIPDB_SUBDIR. It determines the subdir name used in $(PREFIX)/share/ to install the chip database. This provides a mechanism to choose a directory different than icebox (default). I.e. fpga-icestorm/chipdb for Debian. 2016-10-13 21:58:21 +02:00			`CHIPDB_SUBDIR ?= icebox`
