From: Yann E. MORIN Date: Tue, 12 Jul 2011 23:07:45 +0000 (+0200) Subject: toolchain/crosstool-ng: allow pre-downloading the sources X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ea23f34e25839a9559c3bb61cc5d9f54c89e137b;p=buildroot.git toolchain/crosstool-ng: allow pre-downloading the sources On "make source", just download the required sources, and do not build the entire toolchain. This requires a new patch against crosstool-NG (got from upstream). The "uclibc-source" rule requires an installed and configured crosstool-NG, so it has to be after the variables declaration. For consistency, move down the main rule "uclibc". Signed-off-by: "Yann E.
