+Subject: [PATCH] parser/Makefile: dont force host cpp to detect reallocarray
+
+In cross build environments, using the hosts cpp gives incorrect
+detection of reallocarray. Change cpp to a variable.
+
+fixes:
+parser_misc.c: In function 'int capable_add_cap(const char*, int, unsigned int, capability_flags)':
+| parser_misc.c:297:37: error: 'reallocarray' was not declared in this scope
+|   297 |   tmp = (struct capability_table *) reallocarray(cap_table, sizeof(struct capability_table), cap_table_size+1);

Applied to master, but after moving the patch to package/libapparmor/,
renumbering it 0002. It also gets applied to apparmor due to the
symlink package/apparmor/3.0.0 -> package/libapparmor/3.0.0 that I
created.

Best regards,

Thomas
