From 2c23e937660f43131f68f6cbf2ff3fe3d0417032 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 2 Oct 2011 21:20:09 +0200 Subject: external toolchain: slightly optimize the copy of the toolchain sysroot The sysroot of an ARM CodeSourcery toolchain takes about 1.4 GB of space, but 1.1+ GB of this space consists in locale-related information which Buildroot doesn't use. By skipping the copy of those unused files, we save quite a bit of time while importing the toolchain sysroot. Signed-off-by: Thomas Petazzoni Reviewed-by: "Yann E.
