Maximilian Bosch 6585c8e80a glibc: make it easier to work with a dev shell
Creating the build directory in `..` may be OK in a sandbox, but this
makes it unnecessarily annoying when trying to work with this in a
source-checkout.

Hence, move the `build/` directory into the source tree.

/*
This function builds just the `lib/locale/locale-archive' file from
Glibc and nothing else. If `allLocales' is true, all supported
locales are included; otherwise, just the locales listed in
`locales'. See localedata/SUPPORTED in the Glibc source tree for
the list of all supported locales:
https://sourceware.org/git/?p=glibc.git;a=blob;f=localedata/SUPPORTED
