libbb: Prevent clang from reading the G pointer before it is assigned
It was observed that getty crashes on RISC-V 64-bit target, with the
busybox binary compiled by clang/LLVM 17 with -O2. Not only getty,
but also some other applets like syslogd/vi are broken too.
Commit 5156b245 ("Make const ptr assign as function call in clang")
introduced XZALLOC_CONST_PTR() to defeat the compiler optimization,
however it only fixed a small number of broken places when compiling
busybox with clang/LLVM. A large number of places remain broken.
This commit treats ASSIGN_CONST_PTR() the same way as XZALLOC_CONST_PTR().
