Recent versions of ICU (64+) provides a tool for configuring ICU
locale data file with finer granularity [1]
Default generated size for libicudata.so.66.1 is ~27M, which is quite
large for embedded systems and all of them may not even need all locale
data.
This patch calls the icudata buildtool during configure on the icudata
and utilizes a filter called 'filter.json` ( empty by default) to
create the data, default behavior should remain same but someone can
add a filter.json in own layer to configure this data, e.g.
{
"localeFilter": {
"filterType": "language",
"whitelist": [
"en",
"de",
"it"
]
}
}
would only generate the locale data for english/german/italian
This would reduce the size of libicudata.so.66.1 to 12M
