The hidden visibility #pragma in inc/arm/efibind.h was meant to inform the compiler that symbols with external linkage are never exported from shared libraries [and thus never preempted] when executing in UEFI context (since UEFI does not support shared libraries). This allows the compiler to generate relative symbol references instead of GOT entries, which is much more efficient since the latter need to be relocated before invoking the entry point of the UEFI app. However, as it turns out, this pragma is leaking into other code that does not run in UEFI context, but simply needs to access data structures that UEFI defines. So make the pragma dependent on whether we are building with -ffreestanding, which is only used for bare metal code such as UEFI.
