Fix compiling to webOS

[cscd98]

Currently fails to build due an issue with dr_mp3

platform/common/dr_libs/dr_mp3.h: In function ‘drmp3_fopen’:
platform/common/dr_libs/dr_mp3.h:3362:17: error: assignment to ‘RFILE *’ from incompatible pointer type ‘FILE *’ [-Wincompatible-pointer-types]
 3362 |         *ppFile = fopen64(pFilePath, pOpenMode);

So switched to MP3 helix (as it is ARM).. 👍

Helix sources aren't provided for licensing issues in the picodrive repo.

Does it need them to compile? I can always look at another fix (it compiles fine atm)

[irixxxx]

No, it compiles in a shard library loader for helix. However, there wouldn't be mp3 sound output without that shard library in place.

OK i'll see about another fix then 👍

I remember having something similar for another lr platform ages ago. Let me try to find it.

[irixxxx]

Look at platform/common/mp3_drmp3.c. In line 13, it checks for libretro VFS usage and cuts out some functions. That would be a good place to add something for this special case.

Defining a wrapper function for fopen64 to use fopen in case it is compiled on webos is probably the simplest method.

Thanks, updated PR 👍

I've adjusted the way CYCLONE_CC/CXX is passed as otherwise it was still picking up the arm compiler instead of the native one.
