Subject: [PATCH] winebuild: Use $CCAS to assemble if found
|
|
|
|
Commit c14bdaf1 made winebuild use Clang to assemble if found.
|
|
|
|
However, just because a user has some version of Clang installed, it
|
|
does not mean that she wants to use Clang to assemble Wine. For example,
|
|
a user who has both Clang and GAS installed may want to use GAS to avoid
|
|
textrels (see https://bugs.gentoo.org/show_bug.cgi?id=455308).
|
|
|
|
This patch allows the user to override which assembler gets used by
|
|
exporting CCAS at Wine configure time; the name CCAS was chosen for
|
|
compatibility with automake's standard AM_PROG_AS macro.
