Bug#492077: debian-installer: avoid searching for libgcc_s.so

[John Reiser <jreiser@BitWagon.com>]

Subject: debian-installer: avoid searching for libgcc_s.so
Package: debian-installer
Version:
Severity: wishlist

*** Please type your report below this line ***
Many executables used by the installer depend on libgcc_s.so.  Searching for
this library (by ld-linux.so just after execve) takes more than 1% of install
time.  The search tries:
   2375 open("/lib/tls/libgcc_s.so.1", O_RDONLY) = -1 ENOENT
   2373 open("/lib/fast-mult/libgcc_s.so.1", O_RDONLY) = -1 ENOENT
   2372 open("/lib/v5l/libgcc_s.so.1", O_RDONLY) = -1 ENOENT
   2372 open("/lib/v5l/fast-mult/libgcc_s.so.1", O_RDONLY) = -1 ENOENT
   2356 open("/lib/tls/v5l/fast-mult/libgcc_s.so.1", O_RDONLY) = -1 ENOENT
   2355 open("/lib/tls/fast-mult/libgcc_s.so.1", O_RDONLY) = -1 ENOENT
   2351 open("/lib/tls/v5l/libgcc_s.so.1", O_RDONLY) = -1 ENOENT
before finding it in /lib.  [Those counts in the first column are for less than
1/3 of base install on a NSLU2 armel-eabi in low-memory mode.]

The search can be avoided, by forcing it to succeed on the first try:
   export LD_LIBRARY_PATH=/lib
Please apply.


The users of libgcc_s.so include:
