F303 Generated .ld missing RAM symbol; won't compile -- Includes fix

[robertdowling]

CubeMX 6.12.1  STM32Cube_FW_F3_V1.11.5 on Linux Fedora 40
---
New "Basic" Makefile project generated .LD file missing RAM symbol and won't compile with this error:

/usr/lib/gcc/arm-none-eabi/14.1.0/../../../../arm-none-eabi/bin/ld:STM32F303RETx_FLASH.ld:56: syntax error
collect2: error: ld returned 1 exit status

Diff against another project suggested these patches. Appears RAM string was somehow empty.  Now it builds
