[Valgrind-developers] [PATCH] amd64-linux regtest: Disable PIE for int3-amd64

[Yao Zi <zi...@di...>]

The inline assembly chunk contains abosulute address references to
zz_int, which isn't practical in PIE files and results in text
relocations. ld.bfd may throw out some warnings, depending on build-time
configuration,

	warning: relocation in read-only section `.text'
	warning: creating DT_TEXTREL in a PIE

and LLVM ld.lld doesn't even allow text relocations by default.

Additionally, dynamic loader of musl-libc doesn't support text
relocations, thus the test will segfault on musl even built successfully.
Let's just apply @FLAG_NO_PIE@ for it and disable PIE.
