4Subject: [PATCH] libxfs: do not try to run the crc32selftest
5
6Even though the crc32selftest is natively compiled (because it is to be
7executed), it fails in cross-compilation as the host may lack the
8required headers, like uuid/uuid.h (e.g. in a minimal environment).
9
10Moreover, running the crc32selftest natively is completely wrong,
11because it passing on the host does not mean it would still pass n the
12target (because endianness or bitness or alignment differences).
13
14So, just disable running the crc32selftest altogether.
15
16Note that there's a remaining bug-in-hiding, because the crc32 table
17generator is natively built, but with the target CFLAGS.
