Some notes on HP PA-RISC assembler

ATLAS presently supports only 32 bit PA-RISC assembly. Such routines should include:

#if !defined(ATL_LINUX_PARISC) && !defined(ATL_HPUX_PARISC)
 #error "This kernel requires PA-RISC assembler!"
#endif

This quick error exit keeps a non-parisc assembler from generating hundreds or thousands of spurious error messages during install.
