libsel4platsupport: fix seL4_DebugPutChar detection

Serial console support can fall back to using seL4_DebugPutChar. But
it does this based on the kernel's CONFIG_DEBUG_BUILD config parameter
which is wrong--the support is actually based on CONFIG_PRINTING which
is implictly enabled when CONFIG_DEBUG_BUILD is set. This is confirmed
by the fact the actual usage of seL4_DebugPutChar is conditional on
CONFIG_PRINTING. Replace CONFIG_DEBUG_BUILD use with CONFIG_PRINTING.

This has the added benefit of fixing sel4test serial server test cases
when a release build is used.

seL4 Libraries

A collection of libraries for working on seL4.

  • libsel4allocman: an allocator for managing virtual memory, malloc memory and cspaces.
  • libsel4bench: a library with utilities for benchmarking on seL4.
  • libsel4debug: a library with utilities for debugging on seL4. Only useful when debugging a userlevel app; potentially hacky.
  • libsel4muslcsys: a library to support muslc for the root task.
  • libsel4platsupport: a wrapper around libplatsupport specificially for seL4.
  • libsel4simple: an interface which abstracts over the boot environment of a seL4 application.
  • libsel4simple-default: an implementation of simple for the master branch of the kernel.
  • libsel4simple-experimental: an implementatoin of simple for the experimental branch of the kernel.
  • libsel4sync: a synchronisation library that uses notifications to construct basic locks.
  • libsel4test: a very basic test infrastructure library.
  • libsel4utils: a library OS - Commonly used stuff, actively maintained: implements threads, processes, elf loading, virtual memory management etc.
  • libsel4vka: an allocation interface for seL4.
  • libsel4vspace: a virtual memory management interface for seL4.
