Add ltrace as first glibc static tool

- Add ltrace (library call tracer) to the toolkit
- Implement glibc static build system with unified log format
- Build ltrace for 13 architectures with available toolchains
- Fix per-architecture build isolation to prevent object file conflicts
- Update README with ltrace documentation
- Add deps-glibc-static and logs-glibc-static to .gitignore
Note: ltrace requires glibc and has limited architecture support
compared to simpler tools. Some architectures fail due to:
- Missing toolchains (xtensa)
- elfutils not recognizing the architecture
- Architecture-specific compilation issues

 **Note on glibc static builds**: Due to glibc's design, "static" binaries built with glibc may still require certain runtime libraries for features like hostname resolution (NSS) and locale support. These tools are provided for environments where glibc is the standard C library.
