make menuconfig command not working

[Izi0ddr]

when i try running make menuconfig it spits out this error message:

/bin/bash: line 1: /media/izi/n3dsxl/linux/buildroot/support/scripts/setlocalversion: Permission denied
/bin/bash: line 1: support/scripts/br2-external: Permission denied

 *** 'make menuconfig' requires the ncurses libraries.

make[2]: *** [Makefile:253: /media/izi/n3dsxl/linux/buildroot/output/build/buildroot-config/dochecklxdialog] Error 1
make[1]: *** [Makefile:961: /media/izi/n3dsxl/linux/buildroot/output/build/buildroot-config/mconf] Error 2
make: *** [Makefile:84: _all] Error 2

And after making all files in the /support/ directory executable it still shows the same error message, and the libncurses-dev package is already installed and already at the newest version, same as the gcc package.

The context being here that i am trying to put linux on 3ds from this git repository so that the 3ds software and linux can live on the sd card and boot seperately with CFW.
