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);
