Grammar and spelling are off; if I were keeping the sentence as-is, I 
would use:

MINGW lacks langinfo.h, which only exists in glibc and musl

But that statement is a lie, since POSIX requires <langinfo.h> and we 
build on BSD systems which use neither glibc nor musl.  So better would be:

mingw lacks the POSIX-required langinfo.h.
