Guard glibc-specific functions using __GLIBC__ define

[Jolmberg]

Hi! I've been compiling and running quicer on alpine, but recent versions no longer compile. I'm a little bit out of my depth here but it seems to be because alpine uses musl instead of glibc and is missing the malloc_trim and malloc_stats functions. These are already protected by the linux define so I'm wondering if you would consider changing that to GLIBC instead.

@Jolmberg thanks for the PR.

Could you fix the formatting and update your branch?
