Subject: [PATCH] Remove unnecessary HAVE_SYS_SYSMACROS_H check

HAVE_SYS_SYSMACROS_H is always true if MAJOR_IN_SYSMACROS.

This way of checking is recommended in autoconf 2.70 documentation:
https://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=blobdiff;f=doc/autoconf.texi;h=4f041bd4e;hp=9ad7dc1c5f02c8ba25b2fe1218bf931c7113a5d5;hb=e17a30e987d7ee695fb4294a82d987ec3dc9b974;hpb=565a6dc50cfa01cec2fb4db894026689cdf4970c

NOTE: currently
      https://www.gnu.org/software/autoconf/manual/autoconf.html is the
      doc for autoconf 2.69.
