<pre>
    Currently, multiple environment variables are not found across various subprojects such as llvm, clang, LLD, and compiler-rt, leading to test failures when using lit's internal shell.

Example of Error in LLVM:
```
'JITDUMPDIR=/usr/local/google/home/harinidonthula/llvm-project/build/test/ExecutionEngine/JITLink/x86-64/Output/ELF_perf.s.tmp': command not found 
```
Example of Error in Clang:
```
RUN: DEFAULT_TRIPLE=`%t/clang --version | grep "Target:" | cut -d ' ' -f2`
```
Example of Error in LLD: 
```
'ZERO_AR_DATE=0': command not found
```
Example of Error in Compiler-rt:
```
'XRAY_OPTIONS=patch_premain=false': command not found
```
