Compiled on X8DTU with 2 physical Intel Xeon E5530 CPU (8C16T)

Source: https://github.com/ibus/ibus

Compile Flags:
CFLAGS="-mtune=generic -Os -pipe -flto"
LDFLAGS="-Wl,-O1"
export CFLAGS LDFLAGS

# Note: CFLAGS "-flto" reduce compile time
# but greatly increase the size of the *.a files
# wich results in the increase of size for ibus-dev

Dependencies:
autogen-dev
automake
bash
compiletc
coreutils
dconf-dev
gettext-dev
gnome-common
gtk2-dev
gtk2-gir
gtk3-gir
gtk-doc
iso-codes
python3.6-pygments
unicode-character-database
unicode-cldr-emoji-annotations
unicode-emoji
vala-dev

## optional check
### some tests could fail because mylocale.tcz may not support the language
### or require a running X server
