From dfe6005daa4a8abef44d8f1b76cfc64044e4ac6e Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Mon, 7 Dec 2015 19:00:36 +0100 Subject: [PATCH] package/xfsprogs: disable crc32selftest xfsprogs generates a crc32 table, and wants to test it. So it builds a native crc32selftest binary. So far, so good; except the host may not have the required headers (uuid/uuid.h), and probably libs (like libuuid). And anyway, testing the table on the host is flawed, as it does not mean it would be correct on the target (due to differences in bitness, endianness, alignment...). So we just disable the crc32selftest for Buildroot.
