Subject: [PATCH] stty: fix compilation on PowerPC architectures

TCGETS2 and termios2 are not available on PowerPC architectures
(powerpc, powerpc64). Add conditional compilation guards to use
regular termios and cfgetospeed() on PowerPC, while maintaining
termios2 support on other Linux architectures.
