`ENTRY` linker script token is unknown

[beyarkay]

I'm trying to use mold for an ARM32 embedded project (so the gcc toolchain is necessarily out of date), and after removing references to the --cref flag which I'm not sure I need, I ran into this problem:

mold: fatal: /[...]/linker.ld:24: ENTRY(Reset_Handler)
                                  ^ unknown linker script token
collect2: error: ld returned 1 exit status
make: *** [/[...]/Makefile:985: /[...]/output.elf] Error 1

I looked around at other issues, and it seems like the mold linker does not intend to support the full linker script? Linking the project takes a long time at the moment, it would be great to use mold, but the ENTRY token is common for embedded applications. (ENTRY explainer)

mold support a limited set of linker script commands. ENTRY is not supported, but you can use the -e command line option instead.
