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.

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