Subject: [PATCH] fix(linux): build deps on older GCC and Ubuntu 22.04 (#15151)

- GMP: name the parameters in the configure probe from
  0001-GMP_GCC15.patch. Unnamed parameters are a hard error on GCC 10
  and older, so configure failed there.
- TBB: turn off the automatic hwloc search so a system libhwloc-dev is
  not picked up.
- scripts/linux.d/debian: run apt update before checking which
  webkit2gtk package exists, and prefer webkit2gtk-4.1 since the build
  requires it. Add automake, which MPFR's autoreconf needs.
