The Tasking ASM information module was added by commit 94df5b6ef1
(Tasking: Add support for several compiler toolsets, 2022-07-20,
v3.25.0-rc1~133^2). However, it appears to have been left from pattern
following and did not actually work with the Tasking assembler.
Update it to work when running the assembler through the compiler
driver `cctc`, which supports extensions `.asm` and `.src`.
Fixes: #26425
