[FFmpeg-devel] [RFC PATCH 2/2] configure: disable locale use in spa plugin

[Abhishek Ojha <abhishek.ojha@savoirfairelinux.com>]

This commit requires to resolve the compilation error of pipewiregrab
because Pipewire's spa plugin is requesting locale_t extension to
compile.
Which was added in POSIX 2008 but ffmpeg is using POSIX 2001 due to
which spa plugin complains. __LOCALE_C_ONLY flag is set to disable
the locale usage in spa plugin. Adding it in configure file fix both
the library test and source compilation issue.
Not sure if this is the right approach to fix the issue.
Feedback/Suggestions will be highly appreciated.
