maybe -x assembler should be passed to gcc when source file is a assembly file

[Freed-Wu]

add_rules("mode.debug", "mode.release")

target("main")
do
    set_kind("binary")
    add_ldflags("-nostdlib")
    add_files("src/*.asm")
end

Will not work, due to gcc doesn't recognize *.asm

❯ gcc -c src/main.asm
gcc: warning: src/main.asm: linker input file unused because linking not done
❯ gcc -c src/main.S
# work

However, https://github.com/xmake-io/xmake/blob/dev/xmake/languages/asm/xmake.lua#L23

language("asm")
    add_rules("asm")
    set_sourcekinds {as = {".s", ".S", ".asm"}}

Allow extension is *.asm.
Maybe we should add -x assembler to gcc?

you should use .S, .asm is usually used for msvc
