With high -j parallelism the autofdo tests can randomly fail.
autofdo uses Linux perf to record profiling data.
Linux perf uses a locked perf buffer. By default it has
around 516k buffer per uid (/proc/sys/kernel/perf_event_mlock_kb).

An individual perf record tries to grab the full 516k,
which makes parallel perf record fail.

This patch limits the perf buffer for individual perf record to 8k.
With the default settings this allows a parallelism of the test
cases of 16, which is hopefully good enough

(if not would need to add some kind of semaphore, or ask
the user to increase the limit as root)

I also removed an unneeded -o perf.data option

Thanks to Marcin to finally spotting the problem.

Passes bootstrap and test on x86_64-linux. Ok for trunk?

    On MIPS, SIGABRT is defined like this:
     #define SIGIOT   6
     #define SIGABRT  SIGIOT
    
    This breaks addsig which tries to append __SIGIOT_ to SIGLIST. Signal
    number 6 is later added to the output and go complains about a
    duplicate signal number.
    
    Fix by recursing once when obtaining the signal number from
    gen-sysinfo.go if the signal is defined as an alias of another signal.
    Also modify the sed expression to 's/.* = //' which is equivalent to
    the original expression but is less misleading given that it might not
    match a number.

    The gc toolchain decides whether a goroutine is a system goroutine by
    comparing startpc to a list of saved special PCs.  In gccgo that
    approach does not work as startpc is often a thunk that invokes the
    real function with arguments, so the thunk address never matches the
    saved special PCs.
    
    This patch fixes gccgo's understanding of system goroutines.  Since
    there are only a limited number of them, we simply change each one to
    mark itself as special.
    
    This fixes stack dumps and functions like runtime.NumGoroutine to
    behave more like gc.  It also fixes the goprint test in the gc
    testsuite.
