After [1] in upstream LLVM, ld.lld's version output is slightly different when the cmake configuration option LLVM_APPEND_VC_REV is disabled.
Before:
Debian LLD 19.0.0 (compatible with GNU linkers)
After:
Debian LLD 19.0.0, compatible with GNU linkers
This results in ld-version.sh failing with
scripts/ld-version.sh: 19: arithmetic expression: expecting EOF: "10000 * 19 + 100 * 0 + 0,"
because the trailing comma is included in the patch level part of the expression. Remove the trailing comma when assigning the version variable in the LLD block to resolve the error, resulting in the proper output:
LLD 190000
With LLVM_APPEND_VC_REV enabled, there is no issue with the new output because it is treated the same as the prior LLVM_APPEND_VC_REV=OFF version string was.
