add LC_ALL=C to sort invocation to fix processing of the Linux commit history

Here's the offending line issue

sort: The strings compared were `"2008-04-20",35,13,"e16b27816462de700f9508d86954410c41105dc2","Roland McGrath <roland@redhat.com>","kernel/ptrace.c"' and `"2008-04-21",1,1,"bc3c26fe65ecaa3fa96844219a9070a3e079697a","Uwe Kleine-K\366nig <Uwe.Kleine-Koenig@digi.com>","Makefile"'.
move the LC_ALL=C assignment to sort (where it's broken)
