Handle numeric address between section name and : in linker scripts

[Abh10705]

I’d like to work on linker‑script support for output section headers that includee a numeric value between the section name and the :.
Concretely, in a script like the Linux module linker script we have lines such as:
__ksymtab 0 : ALIGN(8) { (SORT(___ksymtab+)) }

Right now, Wild parses section names but ignores or mishandles the numeric value (0) that appears between the section name and :. My goal in this issue is:

Parse and store that numeric value as the sections start address expression.

Use it in the layout phase so output sections like __ksymtab get the correct address when such a value is present.
