gnu: ghc: Fix build with binutils ≥ 2.39.

ld warns about exec stack now, making some tests fail.  Fix them (and also
remove an unwarranted exec stack from libHSrts along with it).

* gnu/packages/patches/ghc-9-StgCRunAsm-only-when-needed.patch
* gnu/packages/patches/ghc-testsuite-recomp015-execstack.patch: New patches.
* gnu/local.mk (dist_patch_DATA): Register them.
* gnu/packages/haskell.scm (ghc-8.6, ghc-8.8, ghc-8.10, ghc-9.0, ghc-9.2,
ghc-9.4): Use them.

+Subject: [PATCH] rts/ghc.mk: Only build StgCRunAsm.S when it is needed
+
+Previously the make build system unconditionally included StgCRunAsm.S
+in the link, meaning that the RTS would require an execstack
+unnecessarily.
+
+Fixes #21478.
