# YOU MUST READ THIS FIRST:
# there are _TWO_ sysroot:
# - the build sysroot: cross-compiling a compiler
# - the sysroot: for any cross-compiler
# there are many bugs related to the configuration of those sysroots
# ALWAYS THINK LIKE YOU ARE CROSS-COMPLING A CROSS-COMPILER ("CANADIAN BUILD")
# **** ALWAYS *****
# This is the top level configure for the gcc source tree which actually does
# _global_ configuration and records some specific options you want to pass to
# the configuration stage of the actual gcc and related pieces of software,
# namely to know exactly how the real packages are configured, it is done in
# the top makefile. As of today, you cannot modularize the different
# sub-packages cleanly, coze depending on their configuration, they will use
# some stuff _inside_ the other packages. THIS IS *INSANE BAD DESIGN FOR THE
# CORE OF A GNU/LINUX SYSTEM* since in the middle of all that, *YOU NEED* an
# external component: the glibc!! Proper design: break gcc in ACTUAL modules,
# to make the glibc just one of them, God Damn It!
# native-system-header-dir is relative to sysroot (for a cross compiler)
