On some architectures (such as ARM), gcc will insert implicit calls to memset(). Handle these using the same mechanism as for the implicit calls to memcpy() used by x86. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* gcc sometimes likes to insert implicit calls to memcpy() and
|
|
* memset(). Unfortunately, there doesn't seem to be any way to
|
|
* prevent it from doing this, or to force it to use the optimised
|
|
* versions as seen by C code; it insists on inserting symbol
|
|
* references to "memcpy" and "memset". We therefore include wrapper
|
|
* functions just to keep gcc happy.
