[PATCH] UefiCpuPkg/BaseUefiCpuLib: Use toolchain-specific rodata section name


Marvin Häuser
 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3318

Correctly define the read-only data sections with the
toolchain-specific section name. This hardens image permission
security and may save image space.
