Sanity check ignores rust_args

[YaLTeR]

Describe the bug
Sanity check doesn't pass rustc the rust_args from the cross file.

To Reproduce
For example, this cross file will fail the sanity check because it doesn't pass the --target to rustc, which causes it to pass wrong arguments to the linker.

If I put --target into the rust executable itself, then everything works fine:

[binaries]
c = 'x86_64-w64-mingw32-gcc'
cpp = 'x86_64-w64-mingw32-g++'
ar = 'x86_64-w64-mingw32-ar'
strip = 'x86_64-w64-mingw32-strip'
windres = 'x86_64-w64-mingw32-windres'
exe_wrapper = 'wine'
rust = ['rustc', '--target=x86_64-pc-windows-gnu']

[properties]
sys_root = '/usr/x86_64-w64-mingw32/sys-root/mingw'

[host_machine]
system = 'windows'
cpu_family = 'x86_64'
cpu = 'x86_64'
endian = 'little'

Expected behavior
rust_args are passed during sanity check.
