Is it valid to use x86 ld.bfd in termux-build?

Hi.

I have an app that needs
binutils-x86-64-linux-gnu
package to build. Actual
host arch doesn't matter:
this app needs to build a
few x86 asm files, so it needs
this. What's worse, its not
compatible with llvm tools.

I expected it to be troublesome
on termux: termux does have
binutils-cross, but this doesn't
suit, as it is cross-configured for
host arch, which can be eg aarch64,
whereas I need exactly i386 arch.

Now what was my surprise when
this app built w/o any problems at all,
w/o any deps on cross-binutils even.
It turned out, on termux CI there is
an x86 binutils, regardless of the
host arch (so even on aarch64).
I suspect this is because you run
the CI under the single x86 container,
just cross-compiling for different
arches. And while this is exactly what
I need to get the "offending" app
quickly building, I wonder if it is
legal to rely on such an "oddity"
w/o being able to specify the actual
dep.

So is it ok, or should I instead build
my own i386-binutils, or maybe just
install them from ubuntu? (x86
cross-binutils are available for all
ubuntu arches except risc-v, but
termux doesn't use risc-v anyway).

Oh, it appears binutils-x86-64-linux-gnu
is already installed on termux CI, besides
the main binutils being also x86.
Even if I fail to find where exactly it
is installed in setup-ubuntu.sh, its
definitely there.
So I guess I can use that instead of the
main x86 binutils...
