Subject: [PATCH] compat: Define off64_t as off_t on linux

Subject: [PATCH] compat: off64_t is not defined by musl
This helps compile with latest musl, where off64_t is not defined
unless _LARGEFILE64_SOURCE is defined, on glibc _LARGEFILE64_SOURCE is
defined if _GNU_SOURCE is defined, so the problem is only seen with musl

Upstream-Status: Submitted [https://github.com/lttng/lttng-tools/pull/164]
Signed-off-by: Khem Raj <raj.khem@gmail.com>
Since the project uses AC_SYS_LARGEFILE, which from the autoconf doc:
"arrange for 64-bit file offsets, known as large-file support."
As such, it is safe to assume off_t is 64-bit wide. This is checked by a
static_assert to catch any platform where autoconf would let a 32-bit
off_t slip.
