%description
Hare is a systems programming language designed to be simple, stable, and
robust. Hare uses a static type system, manual memory management, and a minimal
runtime. It is well-suited to writing operating systems, system tools,
compilers, networking software, and other low-level, high performance tasks.

%build
# We strip down our default LDFLAGS, as it is directly passed to 'ld' and not
# through gcc or so (e.g. '-Wl,' prefixes must be removed, '-spec' doesn't fit
# in there, etc.).
# Note: --build-id is removed since hare's linker script does not support build
# IDs for the time being ('--build-id=sha1' has no effect, which I believe is
# due to the custom linker script specified by '-T', and located at
# rt/hare.sc - I'm no expert on those things, though).
# Our default LDFLAGS:
# -Wl,-z,relro is ignored ('ignored' warning on usage).
# -Wl,--as-needed - I'm not sure if it had any effect here.
# -Wl,-z,now ('ignored' warning on usage).
# -specs=/usr/lib/rpm/redhat/redhat-hardened-ld could be manually fed to ld
# - would it be ignored?
# -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 is not something that LD can eat.
# -Wl,--build-id=sha1
# -specs=/usr/lib/rpm/redhat/redhat-package-notes' could be manually fed to ld
# - would it be ignored?
