[Bug build/10751] New: GDB 7.0 doesn't build with -arch x86_64

[dusk at woofle dot net]

On Darwin 10.0 (Mac OS 10.6), attempting to build a 64-bit gdb7 with

export CFLAGS="-arch x86_64"
export CXXFLAGS="-arch x86_64"
export LDFLAGS="-arch x86_64"

yields a frustrating last-moment link error:

I can confirm that the bug is present on Mac OS X 10.6.2. 

There is a related MacPorts bug report at http://trac.macports.org/ticket/19871#comment:17

Note: why does it say the target amd64-apple-darwin10.0.0 when the error appears compiling it on an 
Intel CPU (as present on Mac hardware)? is there a way to disable compiling for AMD64?

That is just the canonical name for this architecture.
Don't worry about it, it doesn't imply that anything has gone wrong.
