From 15caca28da0f634200b80b98228a5dc0646afbd6 Mon Sep 17 00:00:00 2001 From: Ramsay Jones Date: Tue, 5 Feb 2019 02:27:48 +0000 Subject: [PATCH] Makefile: improve SPARSE_FLAGS customisation In order to enable greater user customisation of the SPARSE_FLAGS variable, we introduce a new SP_EXTRA_FLAGS variable to use for target specific settings. Without using the new variable, setting the SPARSE_FLAGS on the 'make' command-line would also override the value set by the target-specific rules in the Makefile (effectively making them useless). Also, this enables the SP_EXTRA_FLAGS to be used in the future for any other internal customisations, such as for some platform specific values. In addition, we initialise the SPARSE_FLAGS to the default (empty) value using a conditional assignment (?=). This allows SPARSE_FLAGS to be set from the environment as well as from the command-line.
