Willy, something goes wrong here...
ammarfaizi2@integral2:~/work/linux.work/tools/include/nolibc$ taskset -c 0 gcc -ffreestanding -nostdlib -nostartfiles test.c -o test -lgcc /usr/bin/ld: /tmp/ccHiYiks.o: warning: relocation against `environ' in read-only section `.text' /usr/bin/ld: /tmp/ccHiYiks.o: in function `getenv': test.c:(.text+0x1f76): undefined reference to `environ' /usr/bin/ld: test.c:(.text+0x1fc3): undefined reference to `environ' /usr/bin/ld: test.c:(.text+0x1ffc): undefined reference to `environ' /usr/bin/ld: test.c:(.text+0x2021): undefined reference to `environ' /usr/bin/ld: test.c:(.text+0x2049): undefined reference to `environ' /usr/bin/ld: warning: creating DT_TEXTREL in a PIE collect2: error: ld returned 1 exit status ammarfaizi2@integral2:~/work/linux.work/tools/include/nolibc$
I suspect it's caused by commit:
commit c970abe796019b3d576fd154a54b94efb35c02b1 Author: Willy Tarreau <w@1wt.eu> Date: Mon Mar 21 18:33:08 2022 +0100
tools/nolibc/stdlib: add a simple getenv() implementation
This implementation relies on an extern definition of the environ variable, that the caller must declare and initialize from envp.

I will take a look deeper on this...
