The default install.sh used by FPC calls samplecfg to create the config file
for the compiler.

samplecfg is located in compiler/utils.

Line 40 and following contain:

# Detect if we have write permission in sysdir.
if [ -w "$sysdir" ] ; then
   echo Write permission in $sysdir.
   fpccfgfile="$sysdir"/fpc.cfg
   fppkgfile="$sysdir"/fppkg.cfg
   defaultfile="$sysdir"/fppkg/default
   compilerconfigdir="-d CompilerConfigDir=$sysdir/fppkg"
   fppkgconfdir=$sysdir/fppkg/conf.d
else
   echo No write premission in $sysdir.
   fpccfgfile="$HOME"/.fpc.cfg
   fppkgfile="$HOME"/.config/fppkg.cfg
   defaultfile="$HOME"/.fppkg/config/default
   fppkgconfdir="$HOME"/.fppkg/config/conf.d
fi

So as you can see, when the user does not have write permissions in /etc or
/local/etc, it will write a config file in the user home directory, exactly
where the compiler will pick it up.

So you see, we've covered the situation you are trying to solve.

It has been so for ages, all you need to do is use what is there correctly.

There is no need to change anything.
