I think you could take advantage of the recipe.hooks feature of the platform.txt file to conditionally override defines and gcc command line arguments on a per sketch basis. This seems to be a fairly new feature (since Arduino 1.6.something) something they added since I last looked to accomplish something like this.
You might approach it like this:
In the stm32 tools directory create a new tool called 'cpif' which copies a file called gcc_options.txt into the build directory if the file exists in the sketch directory or copies /dev/null if it doesn't
$ cat cpif
#!/bin/bash
set -x
echo $0 $*
sketchdir=${1%.*}
dest=${2}/gcc_options.txt
options="$HOME/Arduino/$sketchdir/gcc_options.txt"
if [ -f $options ]
then
cp $options $dest
else
cp /dev/null $dest
fi
In platform.txt you add a recipe hook that is called before starting the build process.
## Compile c files
+recipe.hooks.prebuild.1.pattern=cpif {build.project_name} {build.path} b4all
recipe.c.o.pattern="{compiler.path}{compiler.c.cmd}" {compiler.c.flags} -mcpu={build.mcu} -DF_CPU={build ...
modify the board.txt to use the @file feature of gcc or just add it to the platform.txt for all boards
Nucleo_64.menu.Nucleo_64_board.NUCLEO_F030R8.build.extra_flags=-DSTM32F030x8 @{build.path}/gcc_options.txt
When the user wants to override defines and gcc command line arguments they create a file called gcc_options.txt in the sketch directory. Here I imagine I want to override the F_CPU value
-U F_CPU
-D F_CPU=24000000UL
When I compile it uses the sketch specific defines and overrides.

Sketch uses 7564 bytes (11%) of program storage space. Maximum is 65536 bytes.
Global variables use 4064 bytes (49%) of dynamic memory, leaving 4128 bytes for local variables. Maximum is 8192 bytes.
Of course you would have to make this work with the different OS types. You would also have to deal with finding the users preference sketch home directory. I just hard coded it in the example above to use my $HOME/Arduino directory.
Seems doable (I actually have this working ) if you care to open yourself to all kinds of user problems when they do bad things : )
