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.

Go 1.8 includes a language change (https://golang.org/doc/go1.8#language):
in an explicit conversion from one struct type to another, any field
tags are ignored.
This CL implements this language change in the gofrontend. The tests
for this are in the gc testsuite, which will be copied into the gccgo
repository in due course.
Updates golang/go#16085.

Ensure that the packages vendored into the standard library do not
have the same pkgpath as the actual packages. If we don't, attempts
to build and test the actual packages will get confused. The specific
error I was seeing was import loops, causing some of the packages to
fail to get initialized, causing an obscure run time crash.
