lttng-babeltrace: fix build failure on gcc14 

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.

Support old compilers



Some old compilers do not use C99 as their default C language variant,

for example gcc 4.3.x, which is used on some old machines. When such a

compiler is used, by default, ULLONG_MAX is not visible. Adding

-std=gnu99 is needed to make this definition visible.



In autoconf speak, this translates into the need of using

AC_PROC_CC_STDC instead of AC_PROG_CC. See

http://www.gnu.org/software/autoconf/manual/autoconf-2.65/html_node/C-Compiler.html

for more details.
