armcc 5.0.4.82 on Win7
When armcc links, I get the following error message (formatted by CMake/ninja)
Error: C4365E: Subtool invocation error: Command line too long
This error message is not described for armccor armlink
The command line is as follows (there are more options normally, but I get the error only with the following):
d:\ARM_Compiler_5\5.0.4.82\bin64\armcc.exe --cpu=Cortex-A9 --via=out.rsp -o out.elf
If the file in --via is more than about 32767 bytes, the linking fails.
The command is run from cmd.exe, but armcc should parse the --via file by itself to my knowledge.
A very temporary workaround is to move the objectfiles before linking, so the path can be shortened. Will fail again when number of files increases.

It is a pity the call to armlink with -via fails as well. That must also call something else to do the actual work.
It is possible to create a number of partially linked files which are then all linked together. I see you are saying it is hard to split the make up like that but it might be worth another try.
I had a quick look on the web about the problem and you can see some nasty tricks people have coded to use on Windows besides havng a via file, nothing to help you though I'm afraid.
