How to statically compile libSkiaSharp.so using musl ?

[Vincent-X-Zhang]

Background:

Want to use a statically compiled SkiaSharp running on a highly trimmed linux-x64.

What did i do?

1. git clone mono/SkiaSharp, mono/skia, richfelker/musl-cross-make.
2. make install
3. do bash python3 tools/git-sync-deps in \skia
4. exclude gr_context.cpp in file core.gni (must exclude this file or you will get an error with condition gpu disabled!)
5. gn gen as config:
   Basically refer to url

is_official_build=true
is_debug=false
is_component_build=false
skia_enable_gpu=false
skia_use_dawn=false
skia_use_gl=false
skia_use_vulkan=false
skia_use_metal=false
skia_use_egl=false
skia_enable_ganesh=false
skia_use_system_libpng=false
skia_use_system_libjpeg_turbo=false
skia_use_system_zlib=false
skia_use_system_expat=false
skia_use_freetype=false
skia_use_fontconfig=false
skia_use_icu=false 
skia_use_piex=false 
skia_enable_pdf=false 
skia_enable_svg=false 
skia_use_system_libwebp=false 
cc="/opt/musl-cross/bin/x86_64-linux-musl-gcc" 
cxx="/opt/musl-cross/bin/x86_64-linux-musl-g++" 
extra_cflags=["-static"] 
extra_ldflags =["-static"]

Problem:

It works well and create the file 'libSkiaSharp.so'. But the libSkiaSharp.so dosn't work:

file ./libSkiaSharp.so
./libSkiaSharp.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

What should i do to make it totally statically compile?
