Subject: "checking whether compiler is gcc... no" on a non-English locale
Hello,
musl's ./configure fails to properly detect gcc compiler when running
on a non-English locale.
Output of gcc -v is localized. For example:
$ env LC_ALL=C gcc -v |& tail -1
gcc version 4.9.2 20141224 (prerelease) (GCC)
$ env LC_ALL=ru_RU.utf8 gcc -v |& tail -1
gcc версия 4.9.2 20141224 (prerelease) (GCC)
$ env LC_ALL=fi_FI.utf8 gcc -v |& tail -1
gcc-versio 4.9.2 20141224 (prerelease) (GCC)
Since ./configure attempts to detect gcc by fnmatch-ing output of gcc
-v against the pattern '*gcc\ version*', it fails.
Possible fix:
diff --git a/configure b/configure
index 673d291..e23a269 100755
--- a/configure
+++ b/configure
