bug#29015: LONG_LONG_MAX/MIN not defined on systems using musl libc

[newbluemoon]

On systems using the musl libc LONG_LONG_MAX and LONG_LONG_MIN are not
defined which leads to a compilation error in certain cases. The
following patch replaces these macros with LLONG_MAX and LLONG_MIN
respectively.
