Adwait Godbole 83c11b29a9 tools: fix make host_info flag parsing and config string escaping
Fix incorrect flag handling and string escaping in the `make host_info`
diagnostic target.

Previously, CFLAGS, CXXFLAGS, and LDFLAGS were passed in a form that caused
improper splitting and quoting, which resulted in malformed output and
incorrectly escaped configuration values such as CONFIG_APPS_DIR.

This change ensures that:
- Compilation flags are passed as proper shell strings
- Flags are split correctly using shlex
- Configuration values are escaped exactly once when generating sysinfo.h
- Parsed output matches the contents of the .config file

This change affects diagnostic output only and does not modify the NuttX
build process or generated binaries.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
