s/ar rcu/ar rc/ during linking
The are a few places in Makefile.SH which do (approximately):
rm $libfile
ar rcu $libfile *.o
The 'u' in 'rcu' seems redundant since the old lib file is always deleted
just before being recreated; and more to the point, it generates warnings
on recent Linux builds:
/bin/ar: `u' modifier ignored since `D' is the default (see `U')
This is because the 'u' modifier updates the archive, i.e. only replaces
the objects which are newer in an existing archive. On my Linux system,
ar by default operates in 'deterministic' mode, which means that it
doesn't add timestamps etc (so that repeated builds will give identical
binaries). In this mode 'u' can't work, hence the warning.
So this commit just removes the 'u' flag.
