diffutils: upgrade to 3.6

diffutils-3.5-gcc7.patch is removed as it's merged in this version.

do_configure_prepend is removed to solve the following configure error.

  error: possibly undefined macro: gl_TYPE_WINT_T_PREREQ

A workaround patch is made to fix the following compilation error for glibc.

  error: dereferencing pointer to incomplete type 'const struct rpl_option'

+Subject: [PATCH] Unset need_charset_alias when building for musl
+
+localcharset uses ac_cv_gnu_library_2_1 from glibc21.m4
+which actually shoudl be fixed in gnulib and then all downstream
+projects will get it eventually. For now we apply the fix to
+coreutils
