    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.

Glibc 2.17 made __secure_getenv an officially supported function, and
renamed it secure_getenv. The libgfortran configure has checked for
both of these, per
https://sourceware.org/glibc/wiki/Tips_and_Tricks/secure_getenv.

Unfortunately, while the dynamical library (libc.so) retains the
__secure_getenv symbol for backwards compatibility, the static library
(libc.a) does not. This means that a libgfortran.a compiled against an
older glibc will not work if one tries to link against a newer
libc.a. This creates problems for providing gfortran binary
distributions that work on as many target systems as possible.

Thus, retain the support for __secure_getenv but call it only via a
weak reference.

Regtested on x86_64-pc-linux-gnu.
