Expected behavior

OK, build completed

(looking at the Makefile it's not needed)
This can be resolved with script:

add_to_path=''

find /opt/nodemcu-firmware/tools/toolchains/esp8266-linux-x86_64-*/bin \
  | while read -r ffile
        do
                if [ -d "$ffile" ]
                then
                        continue
                fi
                dir=`dirname "$ffile"`
                add_to_path="$dir"
                file=`basename "$ffile"`
                nfile=`echo "$file"|cut -b 18-`
                if [ -n "$nfile" ]
                then
                        cp "$dir/$file" "$dir/$nfile"
                fi
        done

export PATH="${add_to_path}:${PATH}"

Explanation:
This error "as: unrecognized option '--text-section-literals'" happens because it tries to use 'system' assembler, while it must use assember for esp8266.
To resolve this we go to /opt/nodemcu-firmware/tools/toolchains/esp8266-linux-x86_64-*/bin, and strip the starting part xtensa-lx106-elf- of all files in the directory. Then we add this directory to PATH.

But then I get:

nodemcu.c:25:22: fatal error: platform.h: No such file or directory
lnodemcu.c:25:22: fatal error: platform.h: No such file or directory
loadlib.c:63:19: fatal error: dlfcn.h: No such file or directory

May be now it needs the 'system' compilers, not for esp ones.

[Constantin Kulikov]

OK, looks like if I run (just build command, rather than /bin/bash and then build from inside)
docker run --rm --name 'nmcu-build' -it -v ~/Projects/nodemcu-firmware/nodemcu-firmware:/opt/nodemcu-firmware marcelstoer/nodemcu-build build
Then build succeeds.
