e2fsprogs: fix linking against librt
Our previous patch to link against librt to access clock_gettime() was merged upstreamed... but it lacked a crucial part which makes the whole thing useless: $(CLOCK_GETTIME_LIB) is always empty from a make point of view. This commit adds a patch to e2fsprogs to fix the problem.

Subject: [PATCH] MCONFIG.in: handle CLOCK_GETTIME_LIB
|
||||
|
||||
Commit 62bc243f1bfe623312a350e4cd0d2e17a69aac45 ("fuse2fs: might need
|
||||
librt") added a check for the clock_gettime() to verify whether linking
|
||||
with the librt library is needed or not to use this function.
|
||||
|
||||
However, this commit forgot the change in MCONFIG.in that allows to
|
||||
define the make variable CLOCK_GETTIME_LIB from the CLOCK_GETTIME_LIB
|
||||
variable substituted by the configure script. Due to this, from a make
|
||||
perspective $(CLOCK_GETTIME_LIB) is always empty, and we get link
|
||||
failure on platforms where clock_gettime() is available in librt.
