export: `-B/usr/lib/llvm-13/bin': not a valid identifier

This is my first attempt at building, so bear with me.

Using Linux Mint 20.3, I've installed all of the clang-13 packages from the LLVM Ubuntu repo. The download and subsequent unpacking seems to go OK. The problem is with one of the export statements in build.sh. Here's the output from the export statements leading up to the error:

+ export LLVM_VERSION=13
+ LLVM_VERSION=13
+ export AR=llvm-ar-13
+ AR=llvm-ar-13

./build.sh: line 38: export: `-B/usr/lib/llvm-13/bin': not a valid identifier

Line 38 is this: export CXXFLAGS+=-resource-dir=${_llvm_resource_dir} -B${LLVM_BIN}.

Same error on Debian 11.

I changed build.sh like this:

export CXXFLAGS+="-resource-dir=${_llvm_resource_dir} -B${LLVM_BIN}"
export CPPFLAGS+="-resource-dir=${_llvm_resource_dir} -B${LLVM_BIN}"
export CFLAGS+="-resource-dir=${_llvm_resource_dir} -B${LLVM_BIN}"

Good catch! I'm surprised this hasn't been noticed before now; simple missing quotes...
