zig build-lib -fno-LLVM breaks due to using stale files

Zig Version

0.11.0-dev.1333+d56a65a8c

Steps to Reproduce and Observed Behavior

Consider the following library source (simple one liner is not enough)

// gurka.zig
export fn doit(data: [*]u8, len: usize) callconv(.C) isize {
 var sum: isize = 0;
 var ipos: usize = 0;
 while (ipos < len) {
 const byte: isize = data[ipos];
 const token: isize = byte - 48;
 if (token < 0 or token > 9) break;
 sum = sum + token;
 ipos += 1;
 }
 return sum;
}

The following sequence of commands break:

zig build-lib gurka.zig
zig build-lib gurka.zig -fno-LLVM

output:

Program aborted due to an unhandled Error:
st_name (0x48000000) is past the end of the string table of size 0xfe
[1] 45564 IOT instruction (core dumped) zig build-lib gurka.zig -fno-LLVM

however, the following variant works fine

zig build-lib gurka.zig
rm libgurka.*
zig build-lib gurka.zig -fno-LLVM

(as well as only running the very last command in an otherwise empty dir)

Expected Behavior

No compile-time crash. no dependence on stale outputs from a previous zig build-exe with different compiler flags.

(yes, the actual compiler output of native assembly itself might be incorrect. I fully expect this, as I intend to work on this part myself. I report this as a stumbling block to even sanely compare the output of different code-gen backends)

@bfredl with 0.12.0-dev.2341+92211135 the output is

error: invalid token in LD script: '\x03\x00\x00\x00\x00\x00\x00\x00\x00\x06\xd8\x0b\x00\x00unescape_brace\x00\x0d' (3:0)

error: unexpected error: parsing input file failed with error InvalidLdScript

That is caused by the -fno-llvm without -fno-lld and is unrelated, I'm guessing this was fixed at the latest by #18160 if not earlier.
