Workaround:
Avoid using _symval and use HI16 instead of $HI16
Release Notes:

Hide
The assembler will incorrectly accept the ELF-only relocation operators $HI16 and $LO16 in instructions that expect a 22-bit immediate or symbol, such as MOVL XARn, #22-bit. Further, the assembler will incorrectly emit a 22-bit R_REL22 relocation. In the case of $HI16, this means that the register will be loaded with an incorrect value. The compiler uses the $HI16 and $LO16 operators to implement the _symval() intrinsic. Any code which uses the _symval intrinsic, or uses the $HI16 operator in a 22-bit immediate context may have the incorrect relocation.
