AS variable is wrongly set

[stsp]

It seems termux sets AS
variable to aarch64-linux-android-clang
in termux_setup_toolchain_27c.sh script.
But it should set it to:
aarch64-linux-android-clang -c
as otherwise also linker is invoked, leading
to a build failure (in my case).

Could you share how to reproduce the build failure?

If only on my own CI:
https://github.com/dosemu2/dosemu2/actions/runs/13136822663/job/36662916337

aarch64-linux-android-clang   -o tmp.o tmp.s
ld.lld: error: undefined symbol: main

is what you see near the end of the log.
Had to override AS variable, but this
is a very bad thing to do as now it may
fail on some other environment...

The run with work-around applied:
https://github.com/dosemu2/dosemu2/actions/runs/13136822663/job/36665587806

Here you can see:

aarch64-linux-android-clang -x assembler -c   -o tmp.o tmp.s

somewhere in the middle of a huge log.

I don't know whether setting AS to clang -c will break the build in other cases...

I think someone should just
try a full rebuild with that. If
no regressions - commit and
forget. :)
