Building for DISCO_F746NG on ARM toolchain results in a link warning

Description

Build an application for DISCO_F746NG target will result in a link warning:

[DEBUG] Return: 0
[Warning] @0,0: L3912W: Option 'legacyalign' is deprecated.
[Warning] JfazrC@44,9: 'MBED_RAM_START' macro redefined [-Wmacro-redefined]

[DEBUG] Errors:         ^
[DEBUG] Errors: 2 warnings generated.
[DEBUG] Errors: Finished: 0 information, 1 warning and 0 error messages.

As mentioned this post it probably affects functionality of the application.

Reason is that in the scatter file:

#define MBED_RAM_START              0x20000000
#define MBED_RAM_SIZE               0x50000

But in the generated profile-ld there is the following information:

        "--predefine=\"-DMBED_RAM_SIZE=0x40000\"", 
        "--predefine=\"-DMBED_RAM_START=0x20010000\"",

Hi @RonEld
I confirm the issue.
I tried some time ago #10323 but I didn't get enough time to make it clean.
