I tried moving the -mfpu=vfp -mtune=cortex-a7 options from
SYSCFLAGS to MYCFLAGS. No success. I even tried moving them
to CC so that the makefile had
CC= gcc -std=gnu99 -mfpu=vfp -mtune=cortex-a7
Still no success.

Here is the whole makefile:

# Makefile for building Lua
# See ../doc/readme.html for installation and customization instructions.

# == CHANGE THE SETTINGS BELOW TO SUIT YOUR ENVIRONMENT =======================

# Your platform. See PLATS for possible values.
