The gcc14 machine has a moderately old host gcc, which was causing a recurrent build failure of host-lttng-babeltrace: http://autobuild.buildroot.org/results/492/49216052c161874f41738e41e6e0c89a6dd04000/build-end.log This commit adds a patch to fix this build failure, related to the access of the ULLONG_MAX define on compilers that did not default to the C99 variant of the C language.

Do not call posix_fallocate() on uClibc
|
|
|
|
uClibc does not implement posix_fallocate(), and posix_fallocate() is
|
|
mostly only an hint to the kernel that we will need such or such
|
|
amount of space inside a file. So we just don't call posix_fallocate()
|
|
when building against uClibc.
