Dear Maintainer,
Currently, racket FTBFS on arm64 due to it not being properly defined in the gc
library that is embedded in the package. This fix doesn't completely fix the
FTBFS (the build hangs, just like on ppc64el), but it is a step in the right
direction.
In Ubuntu, the attached patch was applied to achieve the following:
* debian/patches/0002-aarch64.patch: Add support for aarch64 (arm64) in
the gc library (pulled/modified from boehm-gc upstream Git).
Thanks for considering the patch.
Logan Rosen

+Subject: [PATCH] Add AArch64 (64-bit ARM) target support
+
+* include/private/gcconfig.h (AARCH64): New macro (defined only if
+__aarch64__).
+* include/private/gcconfig.h (mach_type_known): Update comment adding
+ARM AArch64 target.
+* include/private/gcconfig.h (NOSYS, mach_type_known, CPP_WORDSZ,
+MACH_TYPE, ALIGNMENT, HBLKSIZE, OS_TYPE, LINUX_STACKBOTTOM,
+DYNAMIC_LOADING, DATASTART, DATAEND, STACKBOTTOM): Define for AArch64.
