This won't work either, as -dT also expects a file name as parameter.

But after re-reading the documentation, if found that the INSERT command
does exactly what I want:

Using the script

| SECTIONS
| {
|   .bootcall_trampoline :
|   {
|     KEEP(*(.bootcall_trampoline))
|   }
| }
| INSERT AFTER .text

I may call the linker with "-T myscript.ld" and everything works as
expected.

Sorry for the noise,
