[PATCH] Use LDFLAGS when testing linker flags

[Nicholas Wilson <nicholas.wilson@realvnc.com>]

Hi,

This is another patch for the WebAssembly build.

In Wasm, we currently need to pass some extra flags to the linker, and LDFLAGS would seem to be a good way to do this.

The patch below tests the linker by passing LDFLAGS on the link line. This ought to be a safe change to make?

Thanks,
Nick
