It appears that with 3.8.1-4, there is an issue with help2man and how
BUILD_DIR is handled.

"help2man: can't get `--help' info from build-llvm//bin/llvm-mc"

The following code sets this early on:

ifeq (${AUTOCONF_BUILD},yes)

BUILD_DIR=Release

endif

However, later on, this is referenced during man page generation:

LD_LIBRARY_PATH=$(DEB_INST)/usr/lib/llvm-$(LLVM_VERSION)/lib/:/usr/lib/*/libfakeroot
help2man --no-discard-stderr --version-string=$(LLVM_VERSION)
$(TARGET_BUILD)/$(BUILD_DIR)/bin/$$f > debian/man/$$f-$(LLVM_VERSION).1;

What this does then, is just mess up this process, adding two slashes. The
path should be be corrected here, maybe in any of the two ways:

1. Adjust the setting of BUILD_DIR, accounting for both cases (yes and no)

2. Use a sed expression ahead of help2man like:


ifeq (${AUTOCONF_BUILD},yes)

VERSION_STRING=$(LLVM_VERSION) $(TARGET_BUILD)/$(BUILD_DIR)

else

VERSION_STRING=$(LLVM_VERSION) $(TARGET_BUILD)

endif


Then later:

LD_LIBRARY_PATH=$(DEB_INST)/usr/lib/llvm-$(LLVM_VERSION)/lib/:/usr/lib/*/libfakeroot
help2man --no-discard-stderr --version-string=$(VERSION_STRING)/bin/$$f >
debian/man/$$f-$(LLVM_VERSION).1;

Going to test this out myself, but the build takes quite a while.
