The appropriate flag for HEASLR (--high-entropy-va) was added in
binutils 2.25.
Also set the image base >4GB so higher entropy gets applied to image
base randomization when used with HEASLR (8 -> 17 bits of
randomization). Windows does this for compatibility because of "latent
pointer truncation issues".

There's no reason for it. ASLR will rebase it regardless so "preventing
collisions" isn't really relevant. This also brings it in line with
what a msvc produced dll will have (an image base of 0x10000000).

Binutils will always strip the relocation information from executable
files even if it needs it (dynamicbase/ASLR). We can work around this
by using the pic-executable flag combined with setting the correct entry
point since apparently ld forgets what that should be. This problem
affects both 32 and 64-bit mingw-w64.

op== is confusing, as it may easily be mistook for an equality check,
while in reality it is doing an assigment to '='.
This patch has the additional benefit of cleaning up 2 warnings from shellcheck.net.

grep is not required for the functionality in this instance.
This avoids an unnecessary fork, and also avoids a duplicated dumpversion call.
Furthermore, it also corrects behavior when no minor version number is present, see e.g

When building SDL with MinGW, it sets -mwindows with the
assumption that the application is a GUI application. If this
is linked without passing -mconsole to configure via
--extra-ldflags, stdout will be silenced from cmd.exe while
running FFmpeg.
The -mwindows flag that causes this behavior is included in the
sdl_libs variable, so append -mconsole there rather than create
an sdl_ldflags case just to insert it (especially if -mconsole
must come *after* -mwindows in order to be effective).

Don't try to detect the float ABI by checking at the toolchain
name or by trying to assemble and link files with eabi_attributes.
This fixes the float ABI detection when building using clang
with -fembed-bitcode, where the current eabi_attributes check
accidentally passes.

On Xcode's clang on OS X, $cc --version will output a 'Configured with:'
line to stderr, which clobbers the configure script output. As this line
serves no further purpose, it should be silenced.
The same applies to apple-gcc 4.2.1, which complains that it can not
understand the kernel version it is running on.
