mktime: need inline

[Bruno Haible]

Hi Paul,

lib/mktime.c has two inline function definitions. So it needs 'inline'
to be supported or defined away. Otherwise, on HP-UX 11, with HP-UX cc,
one gets errors:

        cc -Ae -O -DHAVE_CONFIG_H -I. -I..      -g -c mktime.c
cc: "mktime.c", line 118: error 1000: Unexpected symbol: "int".
cc: "mktime.c", line 163: error 1000: Unexpected symbol: "time_t".

I'm applying this.

        * m4/mktime.m4 (gl_PREREQ_MKTIME): Require AC_C_INLINE.
