[issue28017] bluetooth.h on big endian needs GNU C extensions

[Christian Heimes]

New submission from Christian Heimes:

PPC Fedora build bot is not able to build the _ssl and _socket module. It looks like bluetooth.h is not compatible with std=c99. It uses some GNU C extensions like __extension__, __attribute__((packed)) and __typeof__. The C99 variant -std=gnu99 should do the trick.
