busybox: recover the 1.8/1.10..1.18 ash+hush gap band

alganet · alganet · commit e12a7abdbd79 · 2026-06-28T15:38:01.000-03:00
The band between the buildable 1.2.x island and 1.18 failed on three stacked
musl/toolchain breaks, all fixed in a new shvr_busybox_fix_makefile
(common/busybox.sh), called from ash.sh and hush.sh after extraction and gated
to 1.3 &lt;= version &lt;= 1.18:

1. GNU make &gt;= 4.3 rejects the pre-kbuild "mixed implicit and normal rules"
   (config %config:, / %/:); drop the bare normal target from each.
2. include/platform.h hand-declares intmax_t/uintmax_t/socklen_t (musl defines
   no libc-identity macro), conflicting with &lt;stdint.h&gt;/&lt;sys/socket.h&gt;; force the
   stdint branch and neuter the socklen_t fallback typedef.
3. fdprintf undefined at link (mapped to dprintf only under __GLIBC__; musl has
   dprintf) -- make that guard unconditional. Same break as the old 1.17.x/1.18.x
   exclusion, now folded in.

The gate keeps the 1.2.x island and &gt;=1.19 trees (which have committed checksums)
byte-identical -- verified 1.2.2's platform.h is left untouched.

Recovered (both ash &amp; hush build and run): 1.8, 1.10, 1.11, 1.12, 1.13, 1.14,
1.15, 1.16, 1.17, 1.18. Still excluded: 1.9 and 1.5..1.7 build but segfault at
runtime under musl; 1.3..1.4 fail to build.
