 systools: fix gcc version detecton on non-english locale

 Summary:
 ghc runs 'gcc -v' to check if we run under vanilla gcc
 or disaguised clang by checking for string

     "gcc version <something>"

 But this check does not always work as gcc has that string
 localized via gettext mechanism:

     (some gcc's locale strings)
     be.po-msgstr "версія gcc %s\n"
     da.po-msgstr "GCC version %s\n"
     de.po-msgstr "gcc-Version %s %s\n"
     el.po-msgstr "έκδοση gcc %s\n"
     ...

 To ping gcc to English locale we now override environment
 variable with 'LANGUAGE=en' value.

 Fixes Issue #8825
