Due to the scope of supported BSPs by qemu-user is limited, such
as a segment fault on armv9 after qemu apply commit [target/arm:
Convert LDAPR/STLR (imm) to decodetree][1]

Upstream nodejs have cross compile support, but it needs host and target
have same bit width (e.g. a x86_64 host targeting arrch64 to produce a
64-bit binary). So:
1. If host and target have different bit width, build with QEMU user as usual;
2. If host and target have same bit width, enable notejs cross compile support:
- The build tools of nodejs is GYP[2], set CC_host, CFLAGS_host,
CXX_host, CXXFLAGS_host, LDFLAGS_host, AR_host for host build
which is separated with target build [3]
- Satisfy layer compatibility, set GYP variables in prefuncs of do_configure,
do_compile and do_install other than in recipe parsing
- Add missing native packages to fix library missing on host build
- Rework libatomic.patch, explicitly link to libatomic for clang
conditionally
