term.c: define CMSPAR when a specific termios.h doesn't do it

CMSPAR is defined by bits/termios.h, and glibc has two flavours of it: a
generic one and an architecture-specific one. glibc will install the
architecture-specific one if it exists, otherwise it will install the
generic one. Only Alpha, MIPS, PPC and Sparc have their own
bits/termios.h.

The generic bits/termios.h, as well as the Alpha, PPC and Sparc flavours
do define CMSPAR. However, the MIPS flavour does not define it.

Define CMSPAR to the value from the generic value, which is also the
value known to the Linux kernel for MIPS.
