/*
 * gmp — GNU Multiple Precision Arithmetic Library.
 *
 * Foundation of the compiler chain: mpfr, mpc, and gcc all build against
 * it.  Build-time tools: m4 (processes the architecture asm files) and
 * make.
 *
 * STATIC-ONLY: --disable-shared.  kappa has no activation step yet (no
 * ld.so.conf / rpath wiring), and the rebuild pipeline builds all packages
 * before installing any — so a shared libgmp would be unfindable at runtime
 * by dependents.  Static keeps the whole bootstrap chain self-contained;
 * revisit when kappa gains store activation.
 *
 * DEPENDENCY PATHS: kappa's scheduler builds dependencies into
 * $KAPPA_ROOT/temp/<dep>/destdir/usr before starting dependents, and only
 * installs everything into $KAPPA_ROOT/bin/<hash>/usr afterwards.  The
 * prepare phase resolves each dep from whichever location exists.
