Error in packer-forwarder

• because we depend on musl and there will be a problem in method qsort_r

need to build a patch to fix it 

change
void qsort_r(void *base, size_t nmemb, size_t size,
           int (*compar)(const void *, const void *, void *),
           void *arg);

to
void qsort(void *base, size_t nmemb, size_t size,
           int (*compar)(const void *, const void *));

How to quilt a patch

quilt edit <file> to modify the file
