Actually problem was caused by invalid LD="lld" setting.

`lld` cannot be called directly without specifying its flavor, because `lld` is actually 5 linkers in one file:
https://github.com/llvm/llvm-project/blob/53ff95254df4be3365a0bf4da2677e75ccbf32ba/lld/tools/lld/lld.cpp#L9-L24
https://github.com/llvm/llvm-project/blob/53ff95254df4be3365a0bf4da2677e75ccbf32ba/lld/tools/lld/lld.cpp#L46-L53
https://github.com/llvm/llvm-project/blob/53ff95254df4be3365a0bf4da2677e75ccbf32ba/lld/tools/lld/lld.cpp#L60-L68
https://github.com/llvm/llvm-project/blob/53ff95254df4be3365a0bf4da2677e75ccbf32ba/lld/tools/lld/lld.cpp#L139-L163

Valid values of LD variable (with equivalent meaning) for LLD linker, GNU flavor:
- LD="ld.lld"             (recommended)
- LD="lld -flavor ld"
- LD="lld -flavor ld.lld"
- LD="lld -flavor gnu"
