gzip: Fix build with musl

gzip 1.6 uses an older version of gnulib when cross compiling it treats
fseeko as broken since it cant do runtime checks for it during configure
this only shows up on musl since for glibc since it has special check
for gnu c library, so we aid the system by telling it that fflush on
stdin works well with musl

Use NO_ASM to avoid textrels

Delete charset.alias for musl which is again another issue in gnulib not
knowing musl platform
