We have patch 0016-handle-sysroot-support-for-nativesdk-gcc.patch to handle
sysroot support for nativesdk-gcc, and add %r target_relocatable_prefix
into spec file for nativesdk-gcc relocation. It was used for injected
paths SYSTEMLIBS_DIR
Due to the supported SDKMACHINE includes:
aarch64, i586, i686, loongarch64, ppc64, ppc64le, riscv64, x86_64
Only i586 and x86_64, i686 and x86_64 have multilib relationship,
for i586,i686 and x86_64, this commit:
- Tweak target_relocatable_prefix, set ${root_prefix} to it , and tweak
libdir32 based on ${root_prefix} prefix with "/lib" suffix
- For i686 and i586, hard code `lib' to 32bit osdirname, `lib64' to
libdir64 and 64bit osdirname, whether multlib or not
- For x86_64, use variable baselib to set libdir64 and 64bit osdirnames,
baselib is set to `lib64' for multilib, and `lib' for non multilib
Above setting also covers gcc-nativesdk without multilib
For other situation, the configuration is the same as usual

Fix `cargo build' failded in SDK, the interpreter of dynamical loader
is not right
