libllvmminimal: Add missing Support/ABIBreak.cpp
When building natively on RISC-V, linking the bootstrap clang-tblgen
fails with:
ld: error: undefined symbol: llvm::EnableABIBreakingChecks
>>> referenced by PrettyStackTrace.cpp
>>> PrettyStackTrace.o:(.sdata+0x0) in archive
/usr/obj/usr/src/freebsd-src/riscv.riscv64/tmp/obj-tools/lib/clang/libllvmminimal/libllvmminimal.a
>>> referenced by Signals.cpp
>>> Signals.o:(.sdata+0x8) in archive
/usr/obj/usr/src/freebsd-src/riscv.riscv64/tmp/obj-tools/lib/clang/libllvmminimal/libllvmminimal.a
>>> referenced by Timer.cpp
>>> Timer.o:(.sdata+0x28) in archive
/usr/obj/usr/src/freebsd-src/riscv.riscv64/tmp/obj-tools/lib/clang/libllvmminimal/libllvmminimal.a
This is likely due to Error.h's inclusion of abi-breaking.h. It's
unclear why this only affects RISC-V, but perhaps relates to its more
eager use of .sdata due to the ABI's support for linker relaxations.
Regardless, this is theoretically an issue for all architectures.
