I'm trying to cross compile libmp3lame on ubuntu at certain point it fails and the error log is being truncated so i cant really detect what is happening
the final lines of shell output are:
/bin/bash ../libtool --tag=CC --mode=link /home/rafa/Desktop/missao/ndk17/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc -mfloat-abi=softfp -marm -march=armv7-a -Os -O3 -I/home/rafa/Desktop/m2/build_dir/include -I/home/rafa/Desktop/missao/ndk17/sysroot/usr/include -I/home/rafa/Desktop/missao/ndk17/sysroot/usr/include/arm-linux-androideabi/ -L/home/rafa/Desktop/m2/build_dir/lib -L/home/rafa/Desktop/missao/ndk17/platforms/android-27/arch-arm/usr/lib -L/home/rafa/Desktop/missao/ndk17/sysroot/usr/lib/arm-linux-androideabi -fPIE -L/home/rafa/Desktop/m2/build_dir/lib -L/home/rafa/Desktop/missao/ndk17/platforms/android-27/arch-arm/usr/lib -L/home/rafa/Desktop/missao/ndk17/sysroot/usr/lib/arm-linux-androideabi -fPIE -pie -static -o lame lame_main.o main.o brhist.o console.o get_audio.o lametime.o parse.o timestatus.o ../libmp3lame/libmp3lame.la -lm

how can i force the make to show the complete command instead of /../ to help me know what is happening
=================== UPDATE========================
Trying to make things clear its a very long script to build ffmpeg to android [it fails on compiling libmp3lame
I will try to paste the related fields:

make clean
make

popd
The files it's looking for are under
/home/rafa/Desktop/missao/ndk17/platforms/android-27/arch-arm/usr/lib
but i set this directory on sysroot and also at LDFLAGS and it still cant find it
after testing several configurations I found one that worked, sharing in case someone is facing similar problems

and running with:
