Build failure when targeting `x86_64-pc-windows-gnu` and path contains spaces

[justsmth]

Problem:

When using the prebuilt NASM binaries and the path contains spaces, builds targeting x86_64-pc-windows-gnu fail.

Reported by @s-mayrh here.

I've dug into this some more. The failure only occurs when using the prebuilt NASM objects. This type of build invokes a batch script to retrieve the prebuilt objects. However, I think the build fails just before the script gets executed.

Here's the command and some output:

% AWS_LC_SYS_PREBUILT_NASM=1 cargo build --target x86_64-pc-windows-gnu

Unless I'm reading this wrong, Make is choking on line 117 of build.make (the last line listed below):
