[ptxdist] [PATCH 2/3] host-localedef: Fix build with gcc 5.1

[Bernhard Walle <bernhard@bwalle.de>]

The build of host-localedef fails with lots of argp-related link errors:

| argp-help.o: In function `indent_to':
| argp-help.c:(.text+0x1335): undefined reference to `argp_fmtstream_point'
| argp-help.c:(.text+0x1352): undefined reference to `argp_fmtstream_putc'
| argp-help.o: In function `space':

The problem is the change of the default C standard from gnu89 to gnu11
which changes the semantics of 'inline'. The issue is described in the
Porting guide at https://gcc.gnu.org/gcc-5/porting_to.html. Adding the
'-fgnu89-inline' option fixes the issue.
