  1. make.js: trim excess whitespaces from CFLAGS and LDFLAGS 

    Excess whitespaces in the CFLAGS and LDFLAGS variables cause `gcc` compilation errors like `aarch64-unknown-linux-gnu-gcc: error: No such file or directory`. This is hard to debug and happens because the `.split(' ')` function will create empty `gcc` arguments, if there are any excess whitespaces in the CFLAGS and LDFLAGS environment variables. This can happen when cross-compiling using a 3rd party toolchain, which manipulates/sets the CFLAGS/LDFLAGS variables and accidentally/carelessly puts to many whitespaces in these flags. We better `trim` any whitespaces from the beginning and end of CFLAGS/LDFLAGS strings and match consecutive whitespaces within the strings via a regex instead, to avoid these nasty and hard to spot compilation errors.
