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.
