Fix UCONTEXT detection on ppc_linux26 via include order
param.linux26.h defines USE_UCONTEXT for all Linux platforms for
glibc 2.4 and higher, but it does this by testing __GLIBC__ and
__GLIBC_MINOR__. These are defined by features.h, which is included
by any system header. At least one system header must be included
before those are defined. lwp/process.c was including <afsconfig.h>
and <afs/param.h> before any other headers, leading to those macros
being undefined. Most of the Linux architectures either have their
own implementation or were explicitly defining USE_UCONTEXT in the
per-architecture param file, but ppc_linux26 was relying on the
default.
Fix this by reordering the includes to include the various system
headers before <afs/param.h> and add a comment explaining why.
This previously worked in earlier versions because the old
param.ppc_linux26.h file included <afs/afs_sysnames.h>, which
included "stds.h", which included a system header prior to the check
for ucontext. The new generic param file reverses that order.
