Export a self-consistent drop-in sysroot per arch#5
Merged
Conversation
penguin compiles per-project init.d/*.c drop-ins against a per-arch sysroot: crt startup objects + libc.so + libgcc_s.so.1 + the ld-musl loader. Today the crt comes from the embedded-toolchains image while the libc comes from the dylibs, and those must be the same musl toolchain -- pairing embedded-toolchains crt with penguin-tools' nixpkgs musl libc makes the drop-in crash at startup. Stage igloo_static/sysroots/<arch>/lib/ in each bundle with the crt objects (Scrt1.o, crti.o, crtn.o, crtbeginS.o, crtendS.o) resolved from this arch's own cross cc via -print-file-name, plus libc.so/libgcc_s.so.1 symlinked into the matching dylibs dir. This lets penguin source the whole drop-in toolchain from penguin-tools and drop both the embedded-toolchains crt and hyperfs. Verified the armel bundle stages all five crt objects (correct ARM relocatable ELF) with libc/libgcc resolving into dylibs/armel.

penguin compiles per-project
init.d/*.cdrop-ins against a per-arch sysroot needing crt startup objects +libc.so+libgcc_s.so.1+ theld-muslloader. The crt and the libc must come from the same musl toolchain; pairing the embedded-toolchains crt with penguin-tools' nixpkgs-musl libc makes the drop-in crash at startup (this is what broke penguin's per-arch tests when the integration overwrote the system dylibs).This stages
igloo_static/sysroots/<arch>/lib/in each bundle with:Scrt1.o,crti.o,crtn.o,crtbeginS.o,crtendS.o) resolved from this arch's own crossccvia-print-file-name, andlibc.so/libgcc_s.so.1symlinked into the matchingdylibs/<arch>/.That gives penguin a self-consistent drop-in toolchain sourced entirely from penguin-tools, so it can drop both the embedded-toolchains crt and hyperfs. Verified the armel bundle stages all five crt objects (correct ARM relocatable ELF) with libc/libgcc resolving into
dylibs/armel.Follow-up (penguin side): point the sysroots stage at
sysroots/<arch>, update DYLIB_DIRS to canonical names, remove the hyperfs download.
